Abstract

Fringe scanning for projection moire to be used in measuring thermal deformation of space panels has been realized using a servo-controlled grating. This system can measure deformation of a 1.6 m x 1.6 m white panel with a resolution of 0.3 mm if point-by-point calibration is available. The cyclic thermal deformation testing of a space panel was successfully carried out using this system.
