Abstract
An electrooptic device which comprises an electrooptic material disposed on an optical axis of an optical beam. The beam is linearly polarized in advance. The electrooptic material has opposed two surfaces in parallel with the optical axis and in both sides of the optical axis. A first electrode pair which is composed of electrode films is formed on the two surfaces of the electrooptic material to perform a lens function. And a second electrode pair which is composed of electrode films is formed on the two surfaces of the electrooptic material to perform a deflection function. The first and the second pairs are disposed side by side with each other along the optical axis.
