ABSTRACT:
A roll and pitch motion optical system, particularly for a ground-based flight simulator visual display using a raster-scanned laser optical projector and a concave part-spherical display screen and requiring a wide-angle display. The optical system uses an input concave paraboloidal mirror and an output convex paraboloidal mirror of complementary shape. The intermediate optics comprise a collimator to constrict the display beam envelope, roll and pitch prisms positioned in the constricted area and close to the output mirror and a concave spherical mirror to reflect beams from the pitch prism back onto the output paraboloidal mirror.
