Optical pattern recognition with LAPS-SLM (I) / light addressed photoconductor and smectic C liquid crystal spatial light modulator

Using a hydrogenated amorphous silicon as a photoconductor, the relatively new class of a light addressed photoconductor and SmC* liquid crystal spatial light modulator named LAPS-SLM is presented. The operation and characteristics of LAPS-SLM without using a dielectric mirror is reported.
