Showing papers on "Spatial light modulator published in 1975"
TL;DR: In this paper, the optical control of the birefringence induced in zinc selenide crystals was investigated under pulse excitation conditions and a prototype spatial light modulator based on a ZnSe crystal was constructed.
Abstract: A study was made of the optical control of the birefringence induced in zinc selenide crystals. The photoinduced birefringence was investigated under pulse excitation conditions. A prototype spatial light modulator based on a ZnSe crystal was constructed. The time, contrast, and spectral characteristics of this modulator were studied and the requirements to be satisfied by the control radiation were formulated.
