摘要:
Disclosed herein is an interdigitation-type diffractive light modulator. In the interdigitation-type diffractive light modulator of the present invention, each of a pair of ribbons has a plurality of diffractive branches which are arranged in a comb shape, and the diffractive branches of the ribbons interdigitate with each other. Furthermore, the respective ribbons moves upwards and downwards or, alternatively, one ribbon moves upwards and downwards, so that the diffractive branches of the ribbons which interdigitate with each other form a stepped structure, thus diffracting incident light.
