Abstract :
A binary phase hologram (BPH) is a computer generated hologram that is designed to get a two-dimensional spot array of uniform or arbitrary intensity light as a Fourier-Fraunhofer diffraction pattern. By illuminating the hologram with a collimated laser beam and using a Fourier transform lens located right alter the hologram, the output image is obtained at the focal plane of the lens. We report on a novel scheme of producing full color images using binary phase holograms and three lasers; red, green, and blue.
