Radar apparatus and optical receiver thereof

A radar apparatus has a light receiver that includes a refractive body and a mirror on an opposite surface of the refractive body relative to an incidence surface of the refractive body for receiving an incident light from an outside of the radar apparatus. The refractive angle of the refractive bod...

More Information
Summary:A radar apparatus has a light receiver that includes a refractive body and a mirror on an opposite surface of the refractive body relative to an incidence surface of the refractive body for receiving an incident light from an outside of the radar apparatus. The refractive angle of the refractive body is configured to be smaller than an incident angle of the incident light, and the mirror is configured to reflect at least a portion of the incident light toward a first light receiving element that is disposed on the incidence surface with its light receiving face facing the incidence surface of the refractive body.
