<p>CCD, CMOS, and Vidicon cameras are used to determine the beam profile of lasers everyday all over the world. Many of these systems have been designed by me and I worked for a very large laser company manufacturing and selling them. (thus I know that of which I speak of)<br>
First point I would like to make is please do not believe that there are any"safe" lasers when your eyes are concerned. Scanning a crowd with lasers is one of the most irresponsible acts I have ever seen. The light show folks talk of scanning speed and and power per microsecond to justify this. Don't believe a word of it. A 5 mW laser pointer reflected off the inside of a glass window into your eye may not damage it within the "blink response" but any more time on your retina and your brain will need to fill in for a second "blind spot". Google "laser institute of America"<br>
Second point "legal" lasers: If they are built and marked correctly they are legal. That doesn't make them safe in the hands of idiots. (or children)<br>
And my final point is damage to sensors. It happens all the time. It is a function of laser power and time. The laser beam diagnostics warranties DO NOT cover this. I wish I had ten bucks for every customer that swore that they used the proper attenuation for their beam. <br>
The sun is not much different . . it comes down to spot size...<br>
Hope this helps one of us from having any damage to our eyes. You can buy another camera.<br>
Do not look at: the sun, any direct or reflected laser beam, arc welding, or nuclear blasts.</p>
