ABSTRACT:
A method for converting a 2-D image into a hologram is set forth. An optical scanner system which measures the primary color intensity of a selected pixel and forms an indication thereof is disclosed. The location of the pixel is output as XY coordinate data. The location and color data is stored in memory, and the memory is thereafter retrieved. A pixel is located on a blank, and a laser beam split into four equal segments is focused along four separate pathways to the pixel location. Interference fringes formed at the point of convergence on the blank enables transfer of a single pixel, and multiple pixels are transferred so that the entire image is reproduced.
