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.
Claims11
A distance measurement system comprising
- a laser light source,
- a plurality of distance detectors arranged on a path that is formed as either a serial structure, a tree-shaped structure or a radial array in the space starting from the laser light source,
- a photodetector for detecting the light returned through the path, and
- a distance measuring apparatus for measuring the distance between the laser light source and each distance detector by analyzing the light detected by the photodetector, wherein
- each of the distance detectors returns part of the input light from a starting point side distance detector to the starting point side distance detector by reflection or both reflection and refraction, sends the remaining part of the light to a forefront side distance detector by transmission, reflection, refraction or a combination thereof, and returns the light returning from the forefront side distance detector to the photodetector through the starting point side distance detector by transmission, reflection, refraction or a combination thereof.
