Paper Abstract
For its compact size and light weight, space telescope with deployable support structure for its secondary mirror is very
suitable as an optical payload for a nanosatellite or a cubesat. Firstly the realization of a prototype deployable space
telescope based on tape springs is introduced in this paper. The deployable telescope is composed of primary mirror
assembly, secondary mirror assembly, 6 foldable tape springs to support the secondary mirror assembly, deployable
baffle, aft optic components, and a set of lock-released devices based on shape memory alloy, etc. Then the deployment
errors of the secondary mirror are measured with three-coordinate measuring machine to examine the alignment accuracy
between the primary mirror and the deployed secondary mirror. Finally modal identification is completed for the
telescope in deployment state to investigate its dynamic behavior with impact hammer testing. The results of the
experimental modal identification agree with those from finite element analysis well.
