In this shot, our camera is only few feet away from our Bokode cube and we were able to resolve a dozen or so barcodes. Each pixel in the barcode is 5 microns wide!
The projected images were printed on a plastic transparency and then mounted at a focal distance away from a lens inside of our plastic Bokode cube.
Here is our Bokode cube. It contains the transparency film, a lens, and a red LED to illuminate the film. All we have to do is power the LED!
