レーザ干渉計による移動体の3次元位置・姿勢計測 (第2報)

往復ビーム間に間隔を持つ3次元位置追尾計測法

抄録

An LTS is a very flexible system that measures the 3D position of a moving target statically, dynamically and contactless, at a high sampling rate and automatically tracks the target in a large working space. However, the orientation measurement by LTS is difficult.
Authors developed an LTS which can measure orientation simultaneously with position measurement, but this method needs to keep an interval between the tracking beam from laser interferometer and the reflection beam from the reflector. This LTS can also reduce the influence of the interval quantity over the position measurement during tracking.
This paper proposes a 3D position tracking measurement method which can keep the interval and attains the 3D positions with a revision using the reflection beam. The effectivity of the new 3D position measurement method was confirmed by an experiment with the initial distance measurement method proposed in the previous report.
