Abstract |
Active support scheme may decide the deformation of the optical surface figure of the primary mirror. Two active support schemes have been designed for 1-m primary mirror, and the performance of each support scheme is conducted. Finite element analysis (FEA) is employed to analyze the optical surface figures of the primary mirror, and optimizations are carried out by using ANSYS for each support scheme to obtain the locations of the axial support. When the locations are determined, axial support force sensitivities are calculated for the two support schemes in a case that a single axial support has a force error of 0.5N. The correction ability of the active support system for both of support schemes are analyzed when an arbitrary axial support is failure. Several low order Zernike modes are modeled with MATLAB procedure, and active optics corrections are applied to these modes for the two active supports. Thermal deformation of the mirror is also corrected for the two schemes. |
