Abstract
The distance detector 12b returns part of the light received from the distance detector 12a located at the starting point side by reflection, or reflection and refraction, sends the remaining part of the light to the distance detectors 12b, 12c, 12d and 12e located at the forefront end side by transmission, refraction, reflection or a combination thereof, and returns the returned light from the distance detectors 12b-12e to the distance detector 11a located at the starting point by transmission, refraction, reflection or a combination thereof. By using laser light sources, it is possible to measure the distance from the laser light sources to multiple points or the distance between two points with a high degree of accuracy.
