Laser scans objects in 3D from half a mile away, scientists just need reason to use it

Laser scans objects in 3D from half a mile away, scientists look for excuse to fire it

3D scanning at a range of 0.62 miles? It just became possible, thanks to a laser camera developed by physicists at Heriot Watt University in Edinburgh, UK. You can pretty much see how it works from the images above — laser beams are bounced off the target and the duration of their return journey is measured precisely enough to detect millimeter depth changes even at extreme distances. Speaking of which, the researchers believe they could pump the range up to 10 miles with a bit of extra research, and even shrink the blaster down to make it “fully portable” in less than five years. Who knows, someday it might even work around corners. But there’s a problem: skin doesn’t reflect the beams properly, which means people can’t be accurately scanned unless they also happen to be ringwraiths. As a result, the researchers seem slightly at loss as to what to do with the technology, with their best suggestions so far being watching the growth of foliage or tracking the movement of rocks. We’d try to think up some other ideas, were it not for the distracting and utterly irrelevant Nazgul v Wilhelm video embedded after the break.

US Navy gets laser cannon of their own

When do we see lasers in action? Well, most of the time, lasers are depicted in science fiction movies sometime in the far off future, where mankind has explored the galaxies far and wide, bringing along with them their sense of adventure and warfare (it is inevitable, as the entire universe is atrophying, so resisting conflict would be futile), and in a case of self-defense (or offense for some), a quick laser shot would do the trick nicely. Star Trek has their phasers, while the X-Wings in the Star Wars universe will see lasers shot from the tips of the S-Foils. The thing is, when will such high tech warfare and weaponry arrive on planet earth? It seems that the answer is “in the right here and now”, where the US Navy has already received its very own kind of laser cannon that has made short work of drones bobbing away in a distance, and said laser cannons can be fitted to active warships.

The US Navy will obviously start to fit their own ships that sail the seven seas with lasers, touting that this represents the future of warfare. Also known as the Laser Weapon System or Laws for short, it has seen action in testing areas, shooting down drones, and considering how it relies on electricity to fire, it costs under $1 per shot – which should be as efficient in disabling a small vessel on the sea, and when you compare it to a $475,000 Sidewinder missile, it makes a whole lot more economical sense to implement Laws throughout their fleet, no?

Interestingly enough, the prototype is not expensive either, where it costs less than $40 million to make, which is a drop in the ocean that the US call their defense budget. It will be installed aboard the USS Ponce, where said vessel has been assigned to the status of a floating base in the Middle East, although this is set to happen sometime after October this year. The Navy has hope that incoming missiles will be unable to outmanoeuvre a highly accurate laser beam that is fired at the speed of light, and for the controller, this could very well be a video game of sorts, although real lives are at stake.

Laser Beams Offer Navy Boats Protection

Laser Beams Offer Navy Boats ProtectionHave you ever wondered just how powerful Cyclops’ (of the X-Men fame) optic blasts can be when he unleashes them without his ruby quartz glasses? I guess depending on the writer, the power behind his optic blasts vary, but the idea of firing lasers from a vessel has more or less remained within the realm of science fiction for a long time, at least not until now. It seems that US Navy ships are now capable of being equipped with the relevant equipment that allows them to fire laser beams, making it handy in situations such as burning through an unmanned drone like a blow torch.

The laser weapon will be first deployed in the Persian Gulf, an area where Iranian speedboats as well as UAVs tend to harass US Navy ships from time to time. In fact, the power from the laser beam is variable, and when it is turned down, it can even blind a spy camera. I suppose the biggest advantage would be the cost, considering it costs a mere $40 million to develop, where a single pulse of directed laser energy costs less than $1, which could also neutralize enemy vessels from afar as a $475,000 Sidewinder missile would. There is one drawback though, poor weather would affect the accuracy and power of the laser beam, but I am quite sure they will work things out eventually. Enjoy the video of the laser beam in action after the jump.

US Navy to deploy ship-mounted laser in 2014, blasts drones in the meantime (video)

US Navy to deploy ship-mounted laser in 2014, blasts drones in the meantime (video)

Lasers have been flaunted by the US Navy before, but now it’s announced that 2014 will see the very first solid-state laser deployed aboard a ship, two years ahead of schedule. The USS Ponce, a vessel used as an amphibious transport dock stationed in the Persian Gulf, will get the honor of hosting the prototype Laser Weapon System (LaWS). Not only can the hardware set boats and airborne drones ablaze, but it can also emit a burst to “dazzle” an opponent’s sensors without inflicting physical harm. Sure, it cost roughly $32 million to construct, but the price is expected to fall when it hits wider production, and Chief of Naval Research Rear Admiral Matthew Klunder estimates that it each shot rings up at under $1. It may not be the missile-obliterating free-electron laser that the Navy’s been lusting for, but we’re sure it doesn’t matter much to drones at the end of the beam. Hit the jump to for a video of the contraption in action.

O-Bow Laser Violin

O Bow Laser ViolinIt is taken for granted that generally speaking, Stradivarius violins are among the most sought after in the world, but what really matters is, just which hands is the violin in question being played with? Give a Stradivarius violin to a beginner and you will most probably be better hearing off a cat screeching orchestra, but when a maestro picks it up, now that is art in motion. Here is a rather unconventional take at what a violin could be in the future, thanks to technology lecturer Dylan Menzies who decided to fall back on the clever amalgamation of using software as well as lasers which will translate the positioning, speed and motion of a traditional wooden bow, all into music. In other words, Dylan introduces the O-Bow Laser Violin to the world.

The optical sensor-driven O-Bow will come encased in copper, complete with a groove for the bow, and this system of his will fall back on synthesis software in order to translate data which has been sent from an optical flow sensor, and that will help track the speed, motion and angle of a wooden rod in high resolution as though it is moving across it. Right now, the 5th prototype of the O-Bow has been completed, and it remains to be seen whether something like this will ever hit the market commercially.

NASA readies first laser communications system for LADEE lunar satellite

NASA integrates its first laser communications system into LADEE lunar satellite

NASA has just finish testing and integration of its first high-data-rate laser communications system for the Lunar Atmosphere and Dust Environment Explorer (LADEE). The Lunar Laser Communication Demonstration presents a significant upgrade in existing data communications used in space — with an estimated increase of six times the throughput of the current best radio system. Unlike previous one-way demonstrations, the LCDD uses an infrared beam — in the same way that many land-based fiber networks do — that can be received on Earth by one of three telescopes located in Mexico, California or Spain. It’s not just about upping the data rate, though, as other challenges include keeping that signal good through conditions your ISP (thankfully) won’t normally have to consider, such as pin-point accuracy over 238,900 miles while moving through space. Going forward, the LLCD will play a vital part in NASA’s 2017 Laser Communications Relay Demonstration, a key test of laser-based relay comms in future missions. Back here on Earth, however, we never thought we’d get bandwidth-envy this far out in the sticks.

Caltech self-healing chips can recover from laser blasts, save power while healthy

Caltech selfhealing chips recover from laser destruction, save power in the process

While many scientists have heard the call for self-healing electronics, their previous projects have usually had just a limited capacity to come back from the brink. Caltech has developed an integrated circuit that could take much more of a bruising. Its prototype power amplifier chip has a dedicated circuit and sensors that can change actuators in microseconds if there’s damage, re-optimizing the connections on the spot. And the chip can take a lot of that damage — 76 examples in a penny-sized cluster endured multiple laser strikes in tests (like the one above) while still ticking. The self-healing even helps while everything is in tip-top shape, as it can cut power use by watching for the usual hiccups in load and voltage. So long as Caltech can develop the technology beyond its currently expected niches of communication and imaging, many of our computing devices could eventually take a few bumps and scrapes on the inside, not just their rugged exteriors.

Nokia Lumia 928 possibly seen in Verizon’s system, spoils few surprises

Nokia Lumia 928 possibly seen in Verizon's system, doesn't reveal much more

We know that Verizon is adding at least one more Nokia Lumia to its stable in the near future. However, there’s been little in tangible evidence to suggest just what’s coming to the carrier’s Windows Phone line. A purported leak to Phone Arena from Verizon’s internal product listings could help fill in that picture. It mentions a Lumia 928, and not much else — but Nokia’s naming customs immediately suggest that this will be Big Red’s rumored variant of the Lumia 920, which is currently limited to AT&T in the US. The device isn’t necessarily connected to the RM-860 we saw at the FCC, although it does support murmurs that Verizon wants at least some kind of improvement over the strictly middling Lumia 822. If the 928 is real, we’re mostly left wondering whether or not it will come quickly enough to remain relevant.

LG Cinema Beam short-throw laser projector and 100-inch screen released in Korea

LG Cinema Beam shortthrow laser projector and 100inch screen released in Korea

One of LG’s more surprising product introductions at CES 2013 was its “HECTO” laser projector, which — when combined with its accompanying 100-inch screen — is capable of tossing a 1080p image from just 22-inches away. While we’d heard it’s coming to the US in March, the projector is out in Korea today branded Cinema Beam TV, available for those ready to drop 9 million won ($8,322) on the package. It has a claimed 1,000,000:1 contrast ratio and can accept video via WiDi or Miracast for wireless streaming from a PC or mobile device, while LG also says its laser light source is eco-friendly thanks to a mercury free design and extra long lifetime. The price tag is said to be around $10K when it ships here, apparently the company feels its unique capabilities make it a perfect fit for commercial installations like sports bars, or just high-end home theater customers that value its small footprint.
