Abstract

본 발명은 레이저와 광학계를 이용하여 3차원 물체에 대한 단면 윤곽선(Contour)을 구하기 위한 스캐너(Scanner)에 관한 것으로 종래 방법에 의하면 물체(1, 6)를 180도 회전시켜 뒷면 측정을 추가로 수행해야 되므로 불편하고 이 경우 앞면의 측정데이타와 뒷면의 측정 데이타간의 경계의 문제(Correspond Problem)등을 해결하기가 어려운 단점을 해결하기 위한 것이다.The present invention relates to a scanner for obtaining a cross-sectional contour of a three-dimensional object using a laser and an optical system. According to the conventional method, the back side measurement is further performed by rotating the objects 1 and 6 by 180 degrees. In this case, it is inconvenient to solve the problem of boundary problem between the measurement data on the front side and the measurement data on the back side.

본 발명은 레이저 빔을 면광으로 분배시킨 후 물체 표면에 정확히 정렬(Align)시켜 스캐닝(Scanning)하므로서 상기한 종래의 불편과 단점을 해소하고 완전한 단면 윤곽선을 얻을 수 있도록 한 것으로 단면 윤곽선을 구하기 위한 광학계에 적용한다.The present invention solves the above-mentioned inconveniences and disadvantages of the conventional method by distributing the laser beam to the surface light and then accurately aligns the scanning surface to the object surface to obtain a complete cross-sectional contour. Applies to
