Abstract
The spatial light modulators (SLM) with inside degenerative feedback are described in the work. This feedback is realized by IR extinction of the photoconductivity because of the light falling from the reader beam on the photoconductor that is modulated by the intensity in the correlation with the input image. It is demonstrated in theory that the SLM parameters are improved by degenerative feedback. Basically the characteristics of the output image are determined by the parameters of the input image and do not depend from the intensity of the light reader beam and supplemented voltage practically.
