Camera trashed by LIDAR laser. How about human eyes?
In article fd27b3e2-f9b8-4049-af66-90504d80c1b0
@googlegroups.com, says... https://petapixel.com/2019/01/12/man...ing-car-laser/ They claim that the human eye is protected by the cornea which acts as a filter. I wonder if they could add such a protection filter (against LIDAR lasers) to digital cameras. -- Alfred Molon Olympus E-series DSLRs and micro 4/3 forum at https://tech.groups.yahoo.com/group/MyOlympus/ https://myolympus.org/ photo sharing site |

So it absorbs the IR before it hits the retina, what's the effect of rapid heating on the cornea? Any IR filter strong enough to screen-out a high-power laser hit will make the camera unusable. Why would that be? IR is not a range that is normally included in photographs, so having a removable filter would be a good thing. If someone was intent on taking IR images, just remove the filter and stop shooting self-driving cars. -- best regards, Neil |
