E-BEAM ADDRESSED EMISSIVE SPATIAL LIGHT MODULATOR EMPLOYING ELECTRON TRAPPING MATERIALS
Agency / Branch:
DOD / MDA
The objective of this proposed work is to develop a novel electron beam addressed emissive SLM which combines high performance polycrystalline electron trapping (ET) materials with an advanced field-emitter array. ET materials prossess properties of fast response time (~10 nsec.), high resolution (>100lp/mm) and extremely high contrast ratio (~10 4:1). Field emitter arrays have the merits of electrical-addressability, high space-bandwidth product (SBP), low drive voltage compatible with IC driving circuitry, and high update speed. Based on these two advanced technologies, the proposed SLM combines high resolution (>100 lp/mm), high SBP (~1000x1000), high frame rate (~1 KHz), high contrast ratio (>10 3:1) and low drive voltage (<10 V) in a single device. The additional features of the proposed SLM are its wide variety of operation modes and electrical and optical dual-addressability.
