Infrared-Sensitive Spatial Light Modulator.
Abstract
This final report summarizes a preliminary investigation of an infrared-sensitive spatial light modulator that is designed to respond to write light in the 3 to 5 micrometers wavelength range. The device can be read out with visible light and, as such, is intended to function simultaneously as an image wavelength upconverter and light modulator. The device design employs a thin-film InSb photoconductor that addresses a DKDP crystal which is cooled near the Curie temperature (-51 degrees centigrade) of DKDP. Preliminary results are reported on: thin flash-evaporated films on InSb; the development of the cooled DKDP substrates; design and fabrication of the modulator vacuum cell; theoretical modelling of the device performance.
