Abstract

The present work reports the results of fitting error analysis for the Deformable Secondary Mirrors (DSM) of the Very Large Telescope (VLT). The analysis is performed in terms of residual rms wave-front error, PSF profile, requested actuator position and force stroke. A comparison with an ideal Karhunen-Loeve and Zernike wave-front correctors is also shown. The analysis is based on influence functions simulated by FEA.
