| Zusammenfassung: | To eliminate need for installing and removing a retroreflector such as a prism and a mirror for each measurement.SOLUTION: An optical target device 1 includes an actuator 50 disposed inside a mounting hole 97 formed on an inner wall 98 of a tunnel 99, and a retroreflector 40 connected to the actuator 50. The actuator 50 moves the retroreflector 40 out of the mounting hole 97 to inside of the inner wall 98 and moves the retroreflector 40 so as to store the retroreflector 40 inside the mounting hole 97.SELECTED DRAWING: Figure 2
【課題】本発明は、プリズム及びミラー等のような再帰反射器の設置及び撤去を計測のたびに行わずに済むことを目的とする。【解決手段】光学的標的装置１は、トンネル９９の内壁９８に形成された取付孔９７の内側に配置されるアクチュエーター５０と、前記アクチュエーター５０に連結される再帰反射器４０と、を備える。前記アクチュエーター５０が、前記取付孔９７から前記内壁９８の内側に前記再帰反射器４０を出すとともに前記再帰反射器４０を前記取付孔９７の内側に格納するよう、前記再帰反射器４０を移動させる。【選択図】図２ |
