Abstract

We report a novel scheme of making programmable binary optical elements using the cathode- ray tube coupled liquid crystal light valve (CRT-LCLV) spatial light modulator (SLM). The CRT-LCLV is a kind of electronically addressed SLM. The programmable code can be directly input onto the CRT-LCLV SLM using a microcomputer. The programmable Fresnel lens is as an example of the programmable binary optical elements. The Fresnel lens function is written onto each pixel of the CRT-LCLV spatial light modulator. Experimental results of making programmable binary optical elements using CRT-LCLV spatial light modulator are presented.
