ABSTRACT:
An imaging unit images light on a light receiving element, and includes an optical path shifting element, and a lens arranged on an input side or an output side of the optical path shifting element. The optical path shifting element includes a liquid crystal layer which is applied with an electrical field in a direction approximately parallel to an in-plane direction. The liquid crystal layer is made of a chiral smectic C phase ferroelectric liquid crystal having a homeotropic alignment. The optical path shifting element shifts an optical path of the light input thereto in an optical path shifting direction.
