An optical apparatus includes a deflector configured to deflect illumination light from a light source to scan an object, and configured to deflect reflected light from the object, a light guide configured to guide the illumination light form the light source to the deflector, and configured to guide the reflected light from the deflector to a light receiving element, an optical member having a reflective area that makes first light which is part of the illumination light from the deflector incident on the deflector by reflection, and a controller configured to obtain information regarding the deflector on the basis of information of the first light from the reflective area. In a cross-section including the optical path from the reflective area to the light guide, a width of the reflective area is smaller than a width of the illumination light on the reflective area.

Optical apparatus, on-board system, and movement apparatus

An optical apparatus includes a deflector configured to deflect illumination light from a light source unit to scan an object and to deflect reflected light from the object, and a controller configured to control the deflector. A first divergence angle of the illumination light in a first cross section is larger than a second divergence angle in a second cross section orthogonal to the first section. The controller controls the deflector so that the illumination light moves in the first cross section at a first speed and moves in the second cross section at a second speed higher than the first speed.
