PROJECTION SYSTEM AND PROJECTOR

WIPO Patent Application WO/2022/227663

A1

A projection system and a projector. The projection system comprises a light-emitting module, a light-homogenizing module, a light modulation module, a digital micromirror array, and a projection imaging module. The light-emitting module is configured to emit a light-emitting beam required by the projection system. The light-homogenizing module comprises a light-homogenizing sheet, and the light-homogenizing sheet is configured to perform light homogenizing processing on the light-emitting beam to form a light-homogenizing beam. The light modulation module comprises a first modulation unit, and the first modulation unit is configured to adjust the light-homogenizing beam to be incident to the digital micromirror array. The digital micromirror array is configured to reflect the light-homogenizing beam to form a reflected light beam, and the reflected light beam carries an encoding pattern. The light modulation module further comprises a second modulation unit, and the second modulation unit is configured to reflect at least part of the reflected light beam to the projection imaging module. The projection imaging module is configured to project the reflected light beam to a position to be projected.
