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.
