Space membrane reflector is very promised for optical quality application with the merits of ultra-lightweight and flexible. In order to improve the surface precision of membrane reflectors  the formation and surface shape error of a membrane at uniform load are studied based on the henky-cambell equations of circular membrane. The ANSYS software is used to build an optimization model of membrane reflector surface shape  in which the yield strength is the state variable  the surface load on ten concentric annular regions of the mirror is the design variable  and the minimum RMS between ideal surface and mirror surface is the target function. and the theoretical and experimental result show that RMS and PV of the optimized surfaces are reduced respectively than those before optimization. In a word  this paper offers the theoretical and experimental basis of the polyimide membrane reflector. 2011 IEEE.

Micro-crack is one of the most effective factor to the intensity and service life of optical components. Owing to the micro-crack on surface  actual strength of optical components is reduced severely  even less than ten-percent of its theoretical strength. According to fracture mechanics  the mechanisms of the formation and propagation of micro-crack and the growth theory of sub-critical micro-crack are discussed in the paper firstly. Based on practice  an on-line test method disposing etching holes-the molecule-infiltrating method and the principles of acid-etching method disposing micro-crack are described. Followed by the demolishing mechanism of abrasives and a more reasonable removal redundancy of fine-grinding and polishing during  optical production is given by using abrasives in different-size orderly. 2009 SPIE.
