Abstract
Description
Claims (1)
- 평행광(a)의 투광부(1)와 그 수광부(2)를 대향 배치하고, 양자간에 피검사물인 선조체(b)를 주행시켜서, 선조체의 투영면적의 변동에 의한 수광량의 변화를 취출하는 선조체 표면의 요철 검출 장치에 있어서, 상기 수광부(2)에 투영된 상기 선조체(b)의 그림자(b')의 폭보다 긴 변을 갖는 한쌍의 광전 변환 소자(5)를 상기 선조체의 주행 방향에 따라 일정한 간격으로 병렬 배치하되, 그 각각의 긴 변이 상기 선조체의 주행방향과 직각을 이루도록 하고, 상기 각 광전 변환 소자의 전기출력을 차동증폭기(6)의 입력에 접속하여, 그 차동출력을 취출하는 것을 특징으로 하는 선조체 표면의 요철 검출장치.
