Abstract

A scanner is disclosed which uses an electro-optic deflector to deflect a light beam onto a receiving medium. The deflector comprises a substrate formed of an optical material and a thin film optical waveguide fabricated on a top surface thereof. An array of parallel metallic electrodes are formed on the waveguide. Each of the electrodes is adapted to receive a voltage independently of the other electrodes. When a voltage is supplied to an electrode, a spatial variation in the index of refraction occurs across the thickness of the waveguide, and this spatial variation is used to deflect a light beam. In order to use the waveguide to scan a light beam across the receiving medium, the light beam is supplied to the waveguide in a direction transverse to the electrodes, and a voltage is sequentially supplied to the electrodes.
