Abstract
An optical apparatus includes a light emitter including at least one light emitting element, a light receiver including a plurality of light receiving elements, an optical element including a plurality of microlenses, an optical system including a first telecentric lens, and a processor configured to acquire distance information to an object based on a time required from when the light emitter emits light to when the light receiver receives the light reflected by the object. The number of microlenses is larger than the number of light emitting elements. The plurality of microlenses and the first telecentric lens form an afocal system.
