Optical diffraction patterns and almost-holograms made with a MOPA laser engraving machine
I use a Cloudray MOPA fiber laser to make diffraction gratings, multi-color images from bitmaps, and almost-holograms on stainless steel sheets. I inspect the gratings with an electron microscope, and also create images made from diffraction grating "pixels" where each pixel has controllable pitch and angle. Machine featured in the video ...
