Abstract
An optical device includes a monochromatic light source, a light distribution switching portion configured to transmit monochromatic light emitted from the monochromatic light source in one fan-shaped region among a plurality of fan-shaped regions centered on a central optical axis and block the monochromatic light in other fan-shaped regions, an objective lens, an aperture stop configured to collect reflected light from the object, an imaging lens, which has passed through the aperture stop, a light receiver on an imaging plane formed by the imaging lens and configured to receive the reflected light from the object and photoelectrically convert the received reflected light, and a controller configured to instruct the light distribution switching portion to change a region transmitting light over time, and calculate a normal direction of the object based on an electrical signal photoelectrically converted by the light receiver.
