Abstract
Provided is imaging optical system, including: a first lens array including a plurality of lens rows each having a plurality of lenses arrayed in main array direction, the plurality of lens rows arranged in sub-array direction; and a second lens array including a plurality of lens rows each having a plurality of lenses arrayed in main array direction, the plurality of lens rows being arranged in sub-array direction. The imaging optical system forms an erect image of object in main array cross section, and forms an inverted image of object in sub-array cross section. At least one of first and second lens arrays includes at least one of a scattering and light-shielding portions arranged between adjacent lens rows. D/Rs≤0.2 is satisfied, where D represents length of at least one of scattering and light-shielding portions in sub-array direction, and Rs represents an effective diameter of imaging optical system in sub-array direction.
