- 라인의 제1레이저광을 피측정물에 조사하는 제1레이저광 조사수단과, 상기 제1레이저광 조사수단에 의해 조사되는 제1레이저광에 대해 겹치도록 작은 라인의 제2레이저광을 조사하여 상기 피측정물에 마크를 발생시킴과 동시에 제1레이저광에 대해 조사 각도가 가변인 제2레이저광 조사수단과, 상기 제1레이저광 조사수단 및 상기 제2레이저광 조사수단에 의해 조사되는 제1레이저광 및 제2레이저광의 반사광을 집광하여 상을 검출하기 위한 상검출수단을 가지는 것을 특징으로 하는 광학식 측정장치.
- 라인의 제1레이저광을 조사하는 제1레이저광 조사수단에 의해 피측정물에 제1레이저광을 조사하고, 작은 라인의 제2레이저광을 조사하는 제2레이저광 조사수단에 의해 상기 피측정물에 제2레이저광을 조사하고, 제1레이저광과 제2레이저광을 겹치게 함으로써 상기 피측정물상에 교차형의 마크를 발생시키고, 상기 피측정물로부터의 상기 마크의 반사광을 반사광으로부터 상을 검출하기 위한 상검출수단의 중심을 통과하도록 하면서 상기 마크를 원하는 점으로 수시 이동시킴으로써 상기 피측정물을 측정하는 것을 특징으로 하는 광학식 측정방법.
