Abstract

본 발명은 레이저광 주사장치에 관한 것으로, 종래에는 레이저 광으로 영상을 재현할 때 테두리만을 표시함으로 물체의 양감, 질감을 위한 명암처리 및 바탕색을 재현할 수 없는 문제점이 있었다.The present invention relates to a laser beam scanning apparatus, and in the related art, by displaying only an edge when reproducing an image with a laser beam, there is a problem in that it is impossible to reproduce the amount of an object, contrast for texture, and ground color.

이러한 점을 감안하여 본 발명에서는 수평, 수직 편향 거울을 동기신호에 따라 회전 또는 진동시킴으로써 티브이와 같은 수평라스터 방식을 적용하여 영상의 명암 및 바탕색을 재현하고 공기중에서 레이저광을 주사선으로 사용함으로써 큰 화면의 영상을 재현할 수 있을 뿐아니라 대형 모니터 제작에 적용할 수 있다.In view of this, in the present invention, the horizontal and vertical deflection mirrors are rotated or vibrated according to a synchronization signal, thereby applying a horizontal raster method such as TV to reproduce the contrast and the background color of the image, and use the laser light as the scanning line in the air. Not only can the image on the screen be reproduced, but it can also be applied to the production of large monitors.
