- 고주파 변조된 광빔을 방출하여 측정 대상을 비추는 송신기(1), 측정 대상에 반사된 빔을 검출하는 측정 수신기(2) 및 기준 수신기(3)로 이루어지며 위상 측정 원리에 따라 거리 측정을 하는 거리 측정기의 교정을 위한 장치에 있어서,a) 내부의 기준구간(14)이 교정 구간이 되어 송신기(1)에서 방출된 빔의 일부가 기준 수신기(3) 쪽으로 항상 유도됨으로서 기준 수신기(3)에서 검출된 빔과 측정 수신기(2)에서 검출된 빔이 동시에 평가될 수 있으며, 그리고b) 기준 수신기(3)의 전기신호를 수신하는 주파수 혼합기(4)와 측정 수신기(2) 역할을 하는 애벌랜치 포토다이오드 사이에 전기 연결선(5)이 있고, 이 전기 연결선(5)에 고주파 혼합기 주파수가 공급되어, 이 고주파 혼합기 주파수가 애벌랜치 포토다이오드의 바이어스(Uv)에 중첩되고 동시에 주파수 혼합기(4)에도 보내짐으로서 주파수 혼합기(4)에서 저주파 교정 신호(NF-CAL)가 발생하고 애벌랜치 포토다이오드에서 저주파 측정신호(NF-MESS)가 발생하여 이들의 상호 위상 위치가 거리 측정을 위해 구해지는 것을 특징으로 하는 장치.
- 제 1 항에 있어서, 기준 수신기(3)로서 PIN 다이오드가 사용되는 것을 특징으로 하는 장치.
- 제 1 항에 있어서, 기준 수신기(3)가 송신기(1)에 내장되는 것을 특징으로 하는 장치.
- 제 1 항에 있어서, 직접혼합기로서 작동하는 애벌랜치 포토다이오드가 기준 수신기(3)가 됨으로써 주파수 혼합기(4)를 대체하게 되는 것을 특징으로 하는 장치.
- 제 1 항 내지 제 3 항 중의 어느 한 항에 있어서, 주파수 혼합기(4)가 송신기(1)의 변조 주파수와 혼합기 주파수를 발생시키는 혼합기 역할도 동시에 하는 것을 특징으로 하는 장치.
- 제 1 항 내지 제 5 항 중의 어느 한 항에 있어서, 측정 수신기(2)의 작동점 규명을 위해 저주파 변조 LED가 따로 마련되어서 거리 측정이 시작될 때마다 측정 수신기(2)를 공지의 빛 강도로 아주 짧은 시간 동안 비추는 것을 특징으로 하는 장치.
- 제 1 항 내지 제 6 항 중의 어느 한 항에 있어서, 송신기(1)의 빔이 측정 대상 대신에 측정 수신기(2)에 직접 도달하도록 조절될 수 있는 빔 전환장치(20a, 20b)가 마련되는 것을 특징으로 하는 장치.
