An experimental test procedure and associated theoretical formulations are described for the evaluation of spatial light modulators (SLMs) for coherent optical computing. The experimental data included were obtained by us on Hughes liquid crystal and photo DKDP SLMs among others. However, in this paper we address only the general procedures to be used to evaluate SLM performance. The detailed aspects of these tests and their relationships to specific SLMs will be covered in separate papers.
