title: Hadamard transforms of images by use of inexpensive liquid-crystal spatial light modulators.
abstract: Incoherent light imaging by Hadamard transformations by use of an inexpensive spatial light modulator from a liquid-crystal display television is demonstrated. The transforms are implemented by means of S matrices. Good-fidelity 31 x 33 pixel images are obtained. The image distortions caused by the limitations of the spatial light modulator are discussed.
