Abstract

This paper describes the photogrammetry method as a mean to measure the deformation of the 6-meter carbon fiber reinforced plastic (CFRP) Platform of the AMiBA interferometric array telescope installed at the Mauna Loa Observatory, Hawaii. The Platform was surveyed at a series of elevation, azimuth and polarization angles. Photogrammetry demonstrates that the deformation of the Platform is not only gravity-induced but also due to the Hexapod mount actuator. The measurement results verify the predictions of the Finite Element Analysis (FEA).
