Abstract
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.
