Abstract
Current optimal filter projection methods either do not take explicit consideration of the limited dynamic range nature of the currently available SLMs or need complicated search and calculation process (for optimal gain and phase angle). To better utilize the limited dynamic range of the bipolar- amplitude SLM used in our recently developed grayscale optical correlator, we devise a simple and rather practical way to improve filter's dynamic range compression after using minimum Euclidean distance projection.
