ABSTRACT:
A projecting optical system having a first lens system, on one focal plane of which a first plane is disposed, a light beam deflector disposed on the opposite side of the first plane relative to the first lens system and to deflect light beams in a predetermined direction, and a second lens system which receives light beams from the light beam deflector and collects the same on a second plane disposed on its focal plane, wherein the first and second lens systems have one and the same distortional characteristic, the distortion to be generated in the first lens system is compensated by the distortion to be generated in the second image-forming lens system, irrespective of the deflecting action of the deflector, to thereby sequentially project the image on the first plane onto a predetermined position on the second plane.
