Claims (1)

  1. 평행광의 투광부와 그 수광부를 대향배치하고, 양자간에 피검사물을 선조체를 통과시키고, 선조체의 투영면적의 변동에 의한 수광량의 변화를 취출하는 선조체조면의 요철검출장치에 있어서, 상기 수광부에 투영된 상기 선조체의 투영폭보다 긴 변(邊)을 선조체의 통과 방향과 직각으로 향한 한쌍의 광전변환소자를 선조체의 통과 방향으로 일정한 간격을 두고 배치하고, 상기 각 광전변환소자의 전기출력을 차동증폭기에 입력하여 그 차동출력을 취출하는 것을 특징으로 하는 선조체 표면의 요철 검출장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
