Abstract

레이저임 주사장치를 개시하는바, 이는 레이저 주사장치의 실린더 렌즈와 제1반사거울 사이에 홀로그램렌즈 또는 보정렌즈를 설치함으로써, 전기적 혹은 기계적인 구동장치에 의한 주사장치를 변경하고 레이저빔 스위치 소자의 설치로 인하여 기계적인 진동으로 인한 문제발생 제거와 레이저 빔의 한 주사에 있어서, 각각의 결상점의 연결 시간을 제거시키며, 또한 레이저 빔을 고속주사를 힐 수 있다.Disclosed is a laser-immune scanning device, in which a hologram lens or a correction lens is provided between a cylinder lens of a laser scanning device and a first reflection mirror, thereby changing the scanning device by an electric or mechanical driving device and The installation eliminates the problem caused by mechanical vibration and in one scan of the laser beam, eliminating the connection time of each imaging point, and also makes high-speed scanning of the laser beam.
