抄録

A novel measurement apparatus with extremely high accuracy called Laser Displacement-meter with Long-working-distance (LDL) was developed to measure micro-meter-scale deformation of large space structures in the ground test. The combination of a laser source and a position sensitive detector makes it possible to measure accurately with long working distance. It is confirmed that LDL has the performance with 7 μm error at 6.1m working distance through the thermal deformation test of X-ray telescope satellite: ASTRO-H. Because LDL is compact and portable one, it can be applicable for measurement of other large objects such as buildings, bridges, and so on.
