ABSTRACT:
A light deflecting device comprising a transparent member having an electro-optical effect, and a first and a second electrode provided on opposite surfaces of the transparent member. When a voltage is applied to one of the electrodes, an uneven electric field is formed inside the transparent member.
This uneven electric field varies a refractive index distribution through the transparent member. As a result, light entering the transparent member is deflected inside the transparent member. This light deflecting device may be used in an optical printing head, a rangefinder or a color checker.
