| 发明名称 | Projection apparatus | ||
| 摘要 | A projection apparatus including an image source, an imaging module and a beam splitting module is provided. The image source provides an image beam. The imaging module is disposed on a transmission path of the image beam and has an aperture stop. The beam splitting module is disposed on the transmission path of the image beam and located on or near the aperture stop. The beam splitting module includes a plurality of aperture stop sub-regions, and the beam splitting module separates a plurality of image sub-beams of the image beam irradiating these different aperture stop sub-regions. These image sub-beams respectively propagate towards different directions after travelling to these aperture stop sub-regions. | ||
