Claims (7)
- 테라헤르츠 빔을 스캔하기 위한 대구경 테라헤르츠 MEMS 스캐닝 거울에 있어서,
상기 MEMS 스캐닝 거울은 스프링, 질량 또는 저항 시스템에 따른 소정의 고유 진동수를 가지고, 상기 테라헤르츠 빔에 의한 입력 신호가 상기 고유 진동수와 공진을 일으켜 동작하는 공진기이며,
상기 테라헤르츠 빔을 반사하는 표면에 상기 테라헤르츠 빔의 파장보다 작은 크기의 직경을 가진 다수의 관통홀이 형성되고, 그리고
상기 MEMS 스캐닝 거울의 질량이 10% 이하 감소되도록 상기 관통홀의 개수가 조절되어 형성됨으로써,
상기 테라헤르츠 빔을 스캔할 때 공기 저항이 감소되어 Q-factor가 높아짐에 따라 넓은 구동범위를 가지게 되는 것을 특징으로 하는 대구경 테라헤르츠 MEMS 스캐닝 거울.
