Patent attributes
A laser projection apparatus includes: laser devices; incident optical systems, each of which is supplied with light beam from the laser device; a scanning device for two-dimensionally scanning the light beam; and a projection optical system for projecting the light beam from the scanning device onto a screen; wherein the scanning device includes a resonant drive mirror for performing deflection in a main scanning direction, and the projection optical system includes at least two nonaxisymmetric-shaped reflecting mirrors and a light source image is present between the first mirror, which is most closest to the scanning device, and the second mirror, thereby achieving a laser projection apparatus using a projection optical system which is easy to downsize, has velocity uniformity and has successful projection characteristics and brightness.
