摘要
The present invention relates to a projection system of an ultrashort-throw projector using a plane mirror, comprising: an image device to form an image using a bundle of light generated from a light source; multiple projection lens units to project the image of the image device; and a reflection unit to reflect the image projected by the projection lens units to be projected in a screen, wherein the reflection unit is a plane mirror. More specifically, the projection system of an ultrashort-throw projector is able to project the image in a screen using a plane mirror rather than an aspheric mirror, wherein the plain mirror is used for a head-up display which requires a small volume.
