Abstract
In a vehicle optical radar apparatus according to this invention, assembly properties are improved, limitations on design in mounting the apparatus on a vehicle are canceled, and satisfactory distance measuring performance can be obtained. In this vehicle optical radar apparatus, a light-emitting element is arranged on one end side of a hollow shaft of a pulse motor. A mirror assembly obtained by integrally molding a light-sending mirror and a light-receiving mirror is fixed to the other end of the hollow shaft. A light-receiving element is arranged at a focus position of the light-receiving mirror. A light-sending beam emitted from a light-emitting element is guided to the light-sending mirror through a light-sending lens and the hollow portion of the hollow shaft to be irradiated outside a case. The light-sending beam reflected by an object is reflected from and focused on the light-receiving mirror and then received by the light-receiving element.
