REFLECTOR, DISTANCE MEASUREMENT DEVICE, DISTANCE MEASUREMENT METHOD, DEFORMATION OBSERVATION SYSTEM, AND PROGRAM
To make it possible to accurately observe deformation of a structure.SOLUTION: A distance measurement device of the present invention comprises: a reflector; radiation means for radiating prescribed electromagnetic waves to the reflector; reception means for receiving the electromagnetic waves reflected by the reflector; measurement means for measuring a time till the reception means receives the electromagnetic waves since when the radiation means radiates the electromagnetic waves; and calculation means for, based on the measured time, calculating a distance from the radiation means to the reflector. The reflector includes at least three or more reflection planes whose planar direction is approximately vertical to the radiation direction of the electromagnetic waves, and the reflection planes are formed in a step structure so that the distance vertical to the planar direction from the radiation means differs at each of the planes.SELECTED DRAWING: Figure 1
【課題】構造物の変位を精確に観測できるようにする。【解決手段】本発明の測距装置は、反射板と、反射板に所定の電磁波を照射する照射手段と、反射板により反射された電磁波を受信する受信手段と、照射手段により電磁波を照射してから、受信手段により電磁波が受信されるまでの時間を計測する計測手段と、計測された時間に基づいて、前記照射手段から前記反射板までの距離を算出する算出手段とを備え、反射板は、面方向が電磁波の照射方向に略垂直な反射面を少なくとも３面以上含み、反射面は、照射手段から面方向に垂直な距離が各々の面で異なるように、段差構造により形成される。【選択図】図１
