ABSTRACT:
An optical system is disclosed which has a small size as a whole and capable of suppressing loss in the light amount in a separating member even when a relatively large-sized scanning device and a reflective diffusing member are used. The optical system comprises a scanning optical system including a scanning device which scans a light flux from a light source at a scanning point and a display optical system which leads an image formed by the scanned light flux to an exit pupil of the optical system. An optical path of the scanning optical system and an optical path of the display optical system have a mutually overlapping part, and the optical paths are separated by a separating member. The scanning optical system forms a conjugate point conjugate with the scanning point at substantially a position of the separating member.
