Abstract:
1. A light propagation structure applied to an optical system that modulates light from a light source through a first optical modulation element and each of a plurality of second optical modulation elements, comprising: a first optical modulation element having a plurality of pixels capable of independently controlling light propagation characteristics, an optical separation unit that divides light from the first optical modulation element into light of a plurality of different specific wavelength regions, and a plurality of second optical modulation elements into which the light divided with the optical separation unit respectively enters and have a plurality of pixels capable of independently controlling light propagation characteristics, wherein a relay optical system is provided in the light path of the first optical modulation element and the optical separation unit that forms an optical image of the first optical modulation element on the pixel surfaces of each of the second optical modulation elements.
