dc.description.abstract	A projection apparatus including an illumination system, a light valve, and an imaging system is provided. The illumination system is for emitting an illumination beam. The light valve is disposed on a transmission path of the illumination beam for converting the illumination beam into an image beam. The imaging system includes a projection lens and an electrically tunable focusing lens. The projection lens is disposed on the transmission path of the image beam. The electrically tunable focusing lens is disposed on the transmission path of the image beam. The electrically tunable focusing lens changes a focal length thereof by electricity but not by a mechanism moving positions of lenses.	zh_TW
