Claims (1)
- 測点に置かれた目標物に向けて測距光を出射する光源と、前記目標物で反射して戻ってきた測距光を受光する受光素子と、前記光源が発した測距光を前記目標物まで往復する外部光路と前記光源から前記受光素子に至る内部光路に分ける分割手段と、前記外部光路と前記内部光路とを切り換えるシャッターとを備えた光波距離計において、
前記分割手段は、前記測距光を前記外部光路と前記内部光路とに分割するとともに平行光として前記シャッターを通過させるように構成され、
前記シャッターが、回転軸と、該回転軸に対して対称位置の2箇所に配置されて、前記外部光路と前記内部光路に入射する各測距光を交互に遮断する遮蔽板と、該遮蔽板を配置しなかった2箇所の一方で前記2つの遮蔽板の間に配置されて、低反射率の目標物のときに内部光路へ入射する測距光を減衰させる減衰板とを備え、
前記遮蔽板の頂点を前記回転軸に固定し、該遮蔽板に前記減衰板の両側を接着固定して、前記遮蔽板と前記減衰板が中心角90°の扇形で配置され、前記減衰板の周縁にシャッター位置検出部が設けられたことを特徴とする光波距離計。
