Description of the Related Art Conventionally, when a distance between two points is measured using a lightwave rangefinder, an operator holds a surveying target at the measurement point and outputs light from the lightwave rangefinder installed at the observation point. The orientation of the survey target is adjusted so that it returns to.
The conventional survey targets used in this case are:
There is one that returns light in the same direction as the incident direction by using a glass prism in which one corner of a cube is cut out.
