Autonomous driving: Lidar can severely damage smartphone cameras

a year ago by copacetic to c/automotive

Lidars mounted on cars can destroy camera sensors. The phenomenon is considered the technological equivalent of staring directly into the sun.

But you would need to point your camera directly onto the lidar beam.

The camera would need to have its IR filter removed which some mobile optical zoom lenses seem to have removed?! If the lidar would be stationary it would render the lidar beam unsafe for human eyes as well. Most lidars have a beam that is harmful if pointed directly for a longer period than you would blink if looking directly into something rally bright. Because they are infrared you don't have that reaction. Therefore it is mounted on a very fast moving rotary disc. Most of the time the disc itself is also tilting up and down or refracted by a mirror or glass to get a bigger field-of-view". This article is saying, you can destroy a camera by pointing a laser in the sensor. Yeah, dûh but the lidar won't break it, unless using a zoomed in sensor which seem to have its IR removed in some mobile cams. So yeah it can happen... Edit: looked at the reddit video some phones with IR filter removes from zoomed in lensen can have problems.

The more important question: are automotive cameras also affected? Does it mean the current car cameras get broken when this lidar passes nearby?
