Document Type and Number:
WIPO Patent Application WO/2021/182410
Kind Code:
A1
Abstract:
In the present invention, light from a light source (52) that has reflected off of a spatial light modulator (30) is radiated toward the front of a unit via a projection lens (72), and a light-blocking member (32) that blocks a portion of the reflected light from a reflection control part (30A) is disposed on the unit front side of the spatial light modulator (30). The light-blocking member (32) is configured so that an opening part (32a) having an opening shape of an isosceles trapezoid inverted upside down is formed, and the left-right width of a non-light-blocking region, in which the reflected light from the reflection control part (30A) is not blocked, is narrower at a bottom portion than at a top portion.
