Abstract

PURPOSE: To realize a deflector of high performance at a low cost by providing elastic phase plates at equal intervals along the advance direction of light, transmitting an acoustooptical deflecting medium polished into a single plane, between the acoustooptical deflecting medium and a piezoelectric body.
CONSTITUTION: Acoustooptical deflecting medium 1 which diffracts light with acoustic waves excited inside the medium like optical glass and dielectric crystal is polished into a single plane. Next, acoustooptical deflecting medium is provided with plane-polished piezoelectric body 2, such as lithium niobate, exciting acoustic waves and between acoustooptical deflecting medium 1 and piezoelectric body 2, elastic phase plates 3a, 3b, 4a and 4b differing in acoustic-wave propagation speed are arranged at equal intervals along the advance direction of light transmitting acoustooptical deflecting medium 1. Consequently, the need to mold and polish the acoustooptical deflecting medium by steps is eliminated and highly-coupled piezoelectric crystal plates can be used, so that the ultrasonic-wave light deflector of high performance can be obtained at a low cost.
