# Sampled fourier transform hologram generated by computer.

@article{Lee1970SampledFT, title={Sampled fourier transform hologram generated by computer.}, author={W H Lee}, journal={Applied optics}, year={1970}, volume={9 3}, pages={ 639-43 } }

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