Abstract
To provide a light controller allowing for an enhanced positional precision in assembly of a spatial light modulator and a random phase mask, and to provide a light controller adapted to prevent positional deviations between a spatial light modulator and a random phase mask against impacts or vibrations, allowing for an enhanced operational integrity, a light controller includes a substrate, a light modulation unit disposed on the substrate and configured for modulation of light, and a random phase mask stacked on the light modulation unit on an optical axis of the light modulation unit.
