Abstract

본 발명은 목적은, 손떨림에 의한 각속도 센서로 부터의 검출신호로 부터, 정각센서로 부터의 위치신호를 감산하고, 거듭 이들의 감산결과로 부터 제동코일이 검출한 회전 각속도신호를 각각 감산하여 얻은 신호로 프리즘을 구동함으로써, 프리즘의 비선형성을 완화할 수 있고, 즉 프리즘을 원활하게 구동할 수 있고, 서어보특성의 위상 여유를 증가시켜, 대량생산시에 소자의 어긋남이나 온도특성에의 의존성에 대하여 강하게 할 수 있도록 한다.
본 발명의 구성은, 가변정각 프리즘(7)과, 이것을 구동하는 수단으로서의 마이크로 컴퓨터(20), 액츄에이터(6) 및 (15)와, 가변정각 프리즘(7)의 위치를 검출하는 정각센서(8) 및 (16)과, 손떨림에 의한 각속도를 검출하는 각속도 센서(1) 및 (10),회전 각속도를 검출하는 제어코일(26) 및 (32)를 갖추고, 각속도 센서(1) 및 (10)으로 부터의 검출결과로 부터 정각센서(8) 및 (16) 및 각속도 센서(1) (10)로 부터의 검출결과를 각각 감산하여 얻은 신호로 가변정각 프리즘(7)을 구동하도록 한 것이다.
