ABSTRACT:
A light receiving and emitting unit has a plurality of light sources, a light receiving element, a light control unit, and an optical block. The optical block has at least a first and a second member formed of a material having birefringent property, and a third member interposed between the first and the second member and formed of a material having lower refractive index than the first and the second members. The light control unit has a crystal thin plate, a pair of electrodes formed on the surfaces of the crystal thin plate so as to sandwich the crystal thin plate for applying a voltage to the voltage application area, and a first and a second insulating member for sandwiching the crystal thin plate so as to cover the electrodes.
