SPATIAL LIGHT MODULATOR AND OPTICAL APPARATUS EMPLOYING THE SAME

摘要

PURPOSE: A spatial light modulator and an optical device employing the same are provided to implement the structure where a phase modulation unit and an amplitude modulation unit are laminated between two transparent substrates. CONSTITUTION: A phase modulation unit(30) is prepared between a first transparent substrate(10) and a second transparent substrate(11). The phase modulation unit modulates optical phase. An amplitude modulating unit(50) is prepared between the first transparent substrate and the second transparent substrate. The first control electrode(31) is prepared on one of the first transparent substrate and the second transparent substrate. The phase modulation layer(32) includes a polymer dispersed liquid crystal layer(33).
