dc.description.abstract Slewing Mirror Telescop(SMT) is a subsystem of UFFO(Ultra-Fast Flash Observatory) Pathfinder. SMT has a f/11.4 Ritchey-Chretien telescope of 100mm in aperture. Based on our current understanding for Pre-flight model SMT thermal responses from the thermal-vacuum chamber test, we simulated heat distribution and the structural deformations of FM SMT. We predicted the wavefront error that was subsequently measured by a phase shifting interferometer while the temperature was increased by 5℃. The predicted and resulting SMT FM wavefront error variation are 0.0382 and 0.0369 waves respectively and these tend to satisfy 0.15 waves in system WFE requirement over the operational temperature variation range of 0 ± 7℃. The results prove that SMT is capable of producing the required performance in space orbit environment.s from the thermal-vacuum chamber test, we simulated heat distribution and the structural deformations of FM SMT.
