Abstract
We have demonstrated two-dimensional x-y laser scanning, using a computer controlled, rotating reflective cube. Our particular application was the digitizing of transparent foils and we achieved milliradian resolutions. Our concept may be easily adapted to other industrial vision applications such as scanning products on an assembly line or two-dimensional extensions of bar codes. The reflective cube method described here is less expensive, more simple and more durable than other techniques such as use of planar mirrors mounted on galvanometer rotors.
