Abstract
A projection apparatus including an illumination system and a projection imaging system is provided. The illumination system is adapted to emit an illumination beam, and the illumination system includes a light source module and a light shaping module. The light source module is adapted to emit at least one beam. The light shaping module is disposed on the transmission path of the at least one beam. The at least one beam forms an illumination beam after passing through the light shaping module, and the illumination beam has a light imaging matching angle. The light shaping module includes at least one first lens element. The at least one first lens element is disposed on the transmission path of the at least one beam. The projection imaging system is disposed on a transmission path of the illumination beam. The projection apparatus is suitable for eliminating stray light and crosstalk of images.
