摘要: A technique to determine a real nonnegative function representing the transmittance of synthesized hologram is described. The uses positions samples in record phase information complex wavefront. Synthesized holograms are displayed on flying spot scanner and recorded film. quantized into 256 levels because hardware limitation scanner.
