Computer-generated holograms: A simplified ray-tracing approach
Alan D. Stein, Zhiyue Wang, JOHN S. JUN. LEIGH · Computers in Physics · 1992
A method that allows holograms to be generated by computer is described. The conventional ray-tracing algorithm is simplified by the use of a real-valued numerical simulation instead of making computations for the complex-valued field. Output via a laser printer and conventional photographic methods has yielded excellent fidelity in the reconstructed images of three-dimensional objects with simple geometries. Increasing computation capacity may allow routine application of this real-valued algorithm for displaying Magnetic Resonance Image data.
