OPTICAL DEVICE AND OPTICAL MACHINING SYSTEM USING THE OPTICAL DEVICE

摘要

An optical device which can inscribe a pattern not only to a flat surface but also to a curve surface by using a liquid crystal spatial optical modulator, and which has high optical utilization efficiency; an optical device which can form a cube having a curve surface by using a liquid crystal spacial optical modulator, and which has high optical utilization efficiency; and an optical machining system having high versatility by mounting these optical devices on a robot. The optical device includes at least a coherent light source, a liquid crystal spatial modulator for controlling a wave plane of light from the coherent light source, and means for recording a complex amplitude distribution to the liquid crystal spatial optical modulator.
