Light Beam Projection
The Light Engine produces fairly collimated light.

This weekend we assembled the first of the new lenses (the 3D-360 will use 10 of them). The new lens is bright and sharp. We also assembled a variant of the LED Light Engine for military evaluation.
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).
We spent the last year designing and building a camera and software that can capture images with pixels that are 16-bits deep. It isn’t easy to view these images since most tools expect 8-bit images, so the following routine is used to squeeze the 65,536 values in the 16-bit image down to the 256 values…
I’m using a laser from Home Depot to roughly characterize a lens for Prototype 4B of the 3D-360 scanner. The lens looks like HAL from 2001.
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…
This low power version of the Light Engine is only about 1/20th the intensity of the full system, but that one will not be ready until late February.
