受信装置。[Claims for Utility Model Registration] Rain and snow sensor polarization receiver that projects polarized light beams in a predetermined wavelength band onto a reflective object such as raindrops or snowflakes, and detects the scattering of the polarization plane of the reflected wave from the reflective object. In the device, a polarization splitter that transmits a light beam polarized in a first direction (tentatively referred to as a vertical direction) and reflects a direction perpendicular to the first direction (tentatively referred to as a horizontal direction) in a direction 90 degrees from the incident direction. a beam splitter; a vertical photodetector directly fixed to the output surface of the polarization splitting beam splitter on which the vertically polarized light beam arrives; a horizontal light-receiving element directly fixed to the output surface of the vertical light-receiving element; a receiving lens provided between the polarization separation beam splitter and the reflected light to focus the incident reflected light on the light-receiving surface of the vertical light-receiving element; A rain/snow sensor polarization receiver comprising: an optical filter that is provided between a lens and the polarization separation beam splitter and that attenuates light other than light in the predetermined wavelength band.
