TRANSMISSION TYPE SPATIAL LIGHT MODULATOR AND TRANSMISSION TYPE SPATIAL LIGHT MODULATION ARRAY DEVICE

A transmission type spatial light modulatoris equipped with a minute transparent optical member for deflecting light in a direction different from an incident direction of incident light and emitting the light, a support member for supporting the minute transparent optical member at a midair position so that the light emission face can be inclined with respect to a plane perpendicular to a travel direction of incident light L1, and a driving member for obliquely displacing the minute transparent optical member by an electrical mechanical operation to vary the emission direction of light from the minute transparent optical member.
