Damage to one spot may result in a horizontal or vertical line. However, the combination of laser and contrast detection is bound to be better than a contrast only setup, giving the LG G3 an advantage over most other smartphones. By developing a hybrid system, LG aims to take the best of both worlds, and on paper it sounds like an impressive and useful piece of technology. The authors looked at both pulsed lasers and continuous wave lasers. Search YouTube and other internet sources for videos and pictures of laser-caused damage.

The result is a camera that sees around corners, and it works in real time. Join our Newsletter Get the very best of Android Authority in your inbox.
It even manages to recognize multiple objects based on the dispersal of photons.

This graph shows that damage to a color CMOS sensor starts at around 40, to 60, watts per square centimeter for an exposure of 0. The laser is extremely fast, though, firing as many as 67 million times per second. Since CW lasers are more common for consumer uses such as pointers, handhelds, and light show projectors, we are presenting only the CW laser beam results.
Contrast detection uses the main image sensor, sweeping upwards through increasing levels of contrast to find the difference between adjacent pixels. Shows done at or below the MPE should cause no problem for human eyes.
A good working definition of “eye-safe” is that everyone leaves the show with the same vision they entered — there is no detrimental change to a person’s vision. When it strikes the surface, light is reflected in all directions. More information on laser eye safety ILDA has presented information about audience-scanning laser laeer in the scientific paper “Scanning Audiences at Laser Shows: Google Pixel 3 international giveaway!
So, this is cool science, but what is it good for in real life? Camera sensors acmera, in general, more susceptible to damage than the human eye.
The laser pulse is fired at a surface beyond the corner in the same direction the camera is facing. It might also be used for collision avoidance in cars in the same way laser rangefinders and sonar are used now.
The damage potential is much greater when the entire beam power enters the camera cakera. This appears to be the first published laboratory test of lasers on consumer-type sensors.
Damage to one spot may result in a horizontal or vertical line. Note that not all claims of laser damage are valid. You can think of it a little like radar, but with light. Of course, real world tests will be the best judge. A summary, reprinted by permission of Cranfield University, is available here. Lasers emit concentrated beams of light, which can heat up sensitive surfaces like the eye’s retina and cause damage.

Indirect viewing like this should not cause damage. To give an idea of how this works in practice, a 5 mW laser pointer at a 1 foot distance has an irradiance of 0.
Just like contrast detection, phase detection is another passive way of detecting the optimum focal point. The photons collected by the camera can be used to calculate the size, speed, and location of the object down to a centimeter or two.
The obvious question is then, is it better?

ILDA analyzed video from the camera, and determined the probable cause to be a very bright white light. Search YouTube and other internet sources for videos and pictures of laser-caused damage. This gives some reasons why even shows which are well above the MPE have not caused any apparent eye changes in millions of audience members.
