The scratch-hologram technique might be very useful in reducing the amount of data required for computer-generated holography. The size independence characteristic suggests that billboard-sized holograms wouldn't be impossible to build. Also, an incoherent-light holo-camera is feasible: if an object is illuminated with structured light resembling a dense random starfield and is photographed at 2f distance by a camera having a curved slit-aperature over its lens, and if the resulting plate is used to etch fine lines onto a metal or plastic surface, the result will be a photographically produced "scratch hologram" of the original object.
