摘要： A projection apparatus including an illumination system, a reflective light valve and an imaging system is provided. The illumination system emits an illumination beam. The reflective light valve is disposed on a transmission path of the illumination beam. The imaging system includes a first lens group, a polarization beam splitter and a second lens group. The first lens group is disposed on the transmission path of the illumination beam between the illumination system and the reflective light valve. The polarization beam splitter is disposed on the transmission path of the illumination beam between the illumination system and the first lens group. The polarization beam splitter permits the illumination beam to pass through and travel to the reflective light valve. The reflective light valve modulates the illumination beam to an image beam traveling to the polarization beam splitter. The polarization beam splitter reflects the image beam to the second lens group.
