본 발명은 다수의 초점을 갖는 제2 반사판을 제공하여 유리부의 두께에 따라 서로 다른 초점을 요구하는 자동차에 모두 적용될 수 있는 레인센서를 제공하는바, 보다 바람직하게, 유리부 두께에 따라 위상차를 갖고 전반사되는 반사광을 모두 수광하도록 하는 다초점 제2 반사판을 제공하여 넓은 영역으로 조사되는 반사광을 집광시키며, 수평방향 및 수직방향으로 유입되는 반사광을 다시 반사하여 수광부로 집광되도록 하는 제2 반사판 구성을 포함하는 레인센서를 통해 높은 집광효율을 갖는 다초점 레인센서를 제공하는 기술이다.
A multifocal rain sensor includes: at least one light emitting unit configured to output light; a first reflective plate corresponding to the at least one light emitting unit and disposed at a position spaced apart from the at least one light emitting unit by a predetermined distance; a glass part reflecting light after the light is reflected by the first reflective plate and forming a sensing region; a second reflective plate re-reflecting the light reflected by the glass part; and a light receiving unit configured to receive the light reflected by the second reflective plate. The second reflective plate includes a multifocal reflective plate having a plurality of focuses based on a vertical height of incident light that varies according to a change in thickness of the glass part.
