本文报道了甚大望远镜（VLT）可变形次镜（DSM）的拟合误差分析结果。分析是在剩余均方根波前误差，点扩散函数的轮廓，要求的致动器的位置和力冲程。还示出了与理想的Karhunen-Loeve和Zernike波前校正器的比较。分析是基于有限元模拟的影响函数。
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.
