摘要：
Look-up table (LUT) is a widely used method for computing computer-generated holograms (CGHs) but usually demands a large memory space. For this reason, we propose a new LUT method to produce binary CGHs. We quantized the lookup table, which allowed us to use smaller data types for storage and computation. Simulation results show that this method reduces the memory space, and its speed is at least 3 times faster than the original LUT method without reducing the quality of the reconstructed image.
