The method is a generalization of the well-known concepts of bit plane representation and decomposition for ordinary gray scale digital images and relies on forming a properly weighted superposition of binary SLMs. Imperfections and nonrobust behavior of practical multilevel spatial light modulators (SLMs) degrade the performance of many proposed full-complex amplitude modulation schemes. We propose a generic method, by which, out of K binary (or 1bit) SLMs of size M × N, we effectively create a new 2K-level (or K bit) SLM of size M × N. This method combines several neighboring micro-mirror pixels into a giant single superpixel, in which the light field's amplitude and.
