ABSTRACT:
A compact scanning optical system includes a scanning light beam generator, a detector for deflecting the light beam from the generator in a predetermined direction, a first optical system for forming the light beam from the generator linearly near the deflecting and reflecting surface of the deflector, and a single optical element disposed and having a power between the deflector and a surface to be scanned. The single optical element has a power both in the deflection plane of the light beam deflected by the deflector and a plane orthogonal to the deflection plane and has different powers in the orthogonal planes.
