Abstract

Ground-based testing of large, precision segmented optical systems poses many unique challenges. Among the factors complicating this process is the extreme sensitivity of the system to environmental disturbances typical of the test laboratory. Floor to ceiling thermal gradients, micro-seismic vibrational disturbances, and acoustic noise become increasingly significant influences in the testing of these systems as the dimensions of the optical elements extend into the 10 meter range. An analytical model of the Precision Segmented Reflector (PSR) Test Bed has been used to investigate the influence and significance of known or anticipated test environmental conditions. Results of these analyses and their implications for ground-based testing of large, precision segmented optical systems are presented and discussed.
