Jit Ray Chowdhury attended CES in his capacity as an autonomous vehicle engineer, and while there, snapped a picture of a self-driving car equipped with a LIDAR system from Aeye; he says the LIDAR's laser lanced through his camera's aperture and zapped its optical sensor, burning a permanent spot into it and ruining the camera (Aeye has offered to replace it).
LIDAR systems need to comply with rigorous safety rules to ensure that they don't blind human eyes, but camera eyes are much more sensitive (this is the basis for IR-reflective materials that confuse CCTVs).
Self-driving cars use both conventional cameras and LIDAR to guide themselves so any camera-blinding potential in LIDAR systems on autonomous vehicles could wreak havoc with other nearby cars.
AEye uses 1550nm lasers. And unfortunately for Chowdhury, cameras are not filled with fluid like human eyes are. That means that high-power 1550nm lasers can easily cause damage to camera sensors even if they don't pose a threat to human eyes.
AEye is known for claiming that its lidar units have much longer range than those of competitors. While most lidar makers say their high-end lidars can see 200 or 300 meters, AEye says that its lidar has a range of 1,000 meters. When I talked to AEye CEO Luis Dussan about this claim last month, he said that one factor in AEye's long range is the use of a powerful fiber laser.
"One of the most important things about fiber lasers is that they can be amplified," Dassan said. "Very short pulse, huge amount of signal."

Freedom EV is a free/open software stack intended to replace the software in your electric vehicle, it's been tested on a Tesla Model X and should work on a Model S, if you can get root.
People like this guy waving his gun at a driverless Waymo van in Arizona are attacking self-driving vehicles with rocks, knives, and *their own cars*, sending a message to tech companies like Waymo, which is owned by Alphabet (Google’s parent company). That message is, please go experiment with artificial intelligence in somebody else’s neighborhood.
The era of finance capitalism is marked by a curious shift in the desire of the business world: to get out of the business of making things people use, and into the business of getting money for owning, extracting and/or liquidating things.
High-def cameras are available to anyone and for much less than they were just a decade ago. Even the phones in our pockets can be used to shoot and edit short films. It’s never been easier to be a filmmaker, providing you have the technique. Enter the Film & Cinematography Mastery Bundle, an online boot […]
Breaking into the indie video game market may be easier than you think. It all starts with an idea, and then it’s a matter of finding the right development platform to bring it to life. No matter what that platform is, it’s a good bet that it’s covered in the 2019 Game Dev & Design […]
