    摘要： An electrooptic device having a simple structure that can efficiently increase deflection of a beam is provided. The device includes: an electrooptic crystal (11) having an electrooptic effect; an electrode pair of a positive electrode (12) and a negative electrode (13) for generating an electric field inside the electrooptic crystal; and a power source for applying a voltage between the electrode pair so as to generate a space charge inside the electrooptic crystal. With this arrangement, by using a simple structure, a change in a deflection angle is temporally rapid, and a large deflection angle that cannot be obtained by a conventional electrooptic crystal prism can be acquired at a low applied voltage.

    摘要： To provide a variable-focal length lens capable of altering its focal length at high speed. The variable-focal length lens has an electrooptic material and electrodes formed on an incident surface of light and on an exit surface of the light of the electrooptic material. An optical axis is set so that the light is inputted into a gap where the electrodes of the incident surface are not formed and is outputted from a gap where the electrodes of the exit surface are not formed. A focus of the light that is transmitted through the electrooptic material becomes variable by varying an applied voltage between the electrodes of the incident surface and the electrodes of the exit surface.
