ABSTRACT:
An optical detection device is provided with an optical path dividing section which is disposed on an optical path toward a light receiving surface which receives an optical beam. The optical path dividing section is provided with an aperture section through which an optical beam passes through under condition that an optical axis of the optical beam coincides a predetermined optical axis which is disposed toward the light receiving surface and an optical element which is disposed around the aperture section so as to reflect a part of the optical bam when the optical axis of the optical beam is deviated from the predetermined optical axis. By doing this, it is possible to detect a wide range of light by a simple structure without loss in the optical detection device and the optical system.
