Complex researches optically controlled liquid-crystal spatial-time light modulators on the photoconductivity organic polymer basis

摘要

Abstract: This paper reviews the optical, temporal, and contrast properties of the spatial light modulator (SLM) photoconductivity organic polymerliquid crystal (POP-LC) type at the writing by nanosecond light pulses ($Tau $EQ 10ns, $lambda $EQ 0,53 $mu@m). The modulation effects on LC caused by the birefringence, the holesteric-nematic phase transition, and the dynamic scattering were used. Clear apertures of POP-LC modulators were $phi $EQ 25 mm or $phi $EQ 110 mm.!11
