The Light Engine produces fairly collimated light.
The latest version of the omnidirectional stereoscopic camera system needs LOTS of light, so we made a Light Engine. Here's a picture of it in action. It is VERY bright. I took this picture by pointing the camera in the general direction of the Light Engine while looking the other way.
If you happen to stare into the light engine with one eye.....
Use remaning good eye to find the power switch & turn it off.
I spend most of my day trying to make noise-free images, so it is no suprise that I am also interested in the opposite. Our new camera for Proto-4B can capture nearly 10 frames per second for hours. Now that we have the speed I need we will tune the exposure routines (next week's work).
