ABSTRACT:
A scan-type optical apparatus includes a light source device that emits a laser beam, an electro-optic element that conducts scan of the laser beam emitted from the light source device by varying refractive index distribution in accordance with the level of voltage to be applied, and a light blocking member disposed on an optical path of the laser beam emitted from the electro-optic element when no voltage is applied to the electro-optic element.
