Title: Scanning method of light beam for control
Inventor: SEKIHARA KIYOUICHI
IPC: G02B26/10
Filed: 1982-02-12
Abstract: PURPOSE:To enable plane scanning of a light beam, by changing the refractive indices in the respective parts of a medium contained in a light beam diffraction means periodically thereby changing the diffraction angle of the diffracted light of the light beam made incident to the diffraction means periodically. CONSTITUTION:The piezoelectric oscillator 22 of an acoustooptic modulator 20 inputted with the sweep signal applied from a sweep oscillator 30 generates the sweep signal applied from a sweep oscillator 30 generaes the sweep signal  inputted thereto, and applies said ultrasonic waves to a medium 21. The compressional waves of the ultrasonic waves lead to a periodical change in the refractive index of the medium 21, whereafter the ultrasonic waves are annihilated  by an acoustical material 23. When a laser beam LB is made incident from a  laser beam generator 10 to the modulator 20 in such a state, the change in the  refractive index of the medium 21 acts as a diffraction grating and diffracts the  beam LB. Since the diffraction angle of the diffracted beam LB 1 changes with  a change in the frequency of the sweep signal, the result is that the beam LB 1  is scanned so as to keep the optical axis within the same plane.
