摘要： 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.

摘要： A laser projection apparatus PJ 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 at least one light source image is formed in an optical path ranging from the scanning device to the screen SC, and the projection optical system includes two reflecting mirrors which has such a power that, with respect to the main scanning direction, a positive power thereof becomes increasingly greater toward peripheries of the main scanning direction, and each of the incident optical systems has a power in the main scanning direction and a power in the sub scanning direction, one power being different from another power, 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.
