dc.description.abstract Compensation for spatial light modulator device imperfections can be achieved using digital electronics. Optical computing applications, requiring accurate phase or amplitude modulation, can then make use of low-cost, enhanced devices. Using electronic compensation, corrections can be made for a nonsquare aspect ratio in the aperture window and a nonlinear phase response—which may also be nonuniform over the aperture. The corrections for these imperfections are implemented using low-cost field programmable gate arrays. This technology enables real-time compensation and is easily adapted to suit a wide range of display devices. The performance enhancement is demonstrated using a popular Seiko-Epson liquid crystal television display operating as a phase modulating spatial light modulator. These developments greatly extend the utility of readily available, inexpensive, spatial light modulators. en
