There are three main nonlinear elements in the large mirror assemblies  which are screw pretension  adhesive stress and state changes in the assembly process. The optical shape will be influenced seriously by these factors. But the impacts will not be shown in linear analysis results  because as the simplification  these factors have been ignored. The nonlinear analysis method for predicting optical surface deformations resulted from assembly process is discussed in detail. Take a typical mirror support structure for example  the nonlinear analysis model was established. Comparing the calculation results with the optical shape test  it is illustrated that nonlinear analysis is more accurate and closer to the test result. And according to the simulation result  the bowl-shaped depression which was discovered in the test can also be explained reasonably. 2010 Copyright SPIE - The International Society for Optical Engineering.

Computer Controlled Optical Surfacing (CCOS) is widely used for making optical aspheric mirrors. In the practical fabrication  edge effect is an important problem which restricts the fabrication efficiency and accuracy seriously. In this paper  the edge effect is solved by working out the edge removal function and compensate with dwell time function. Skin Model is used to describe the pressure distribution when the tool hangs over the work-piece. The calculation model of edge removal function is derived from Skin Model theoretically. A removal function experiment is completed. The difference between the theoretical model and the experiment results is less than 5%. It means that the calculation model is suit for the practical fabrication. Than the dwell time is solved with edge effect compensation by matrix-based algorithm. In the end  actual experiment was done to validate the edge effect compensation method. 2010 Copyright SPIE - The International Society for Optical Engineering.

In order to realize real-time auto-focusing for theodolite  lens-apart method was designed with the corresponding math model built and analyzed. An Object beam splitted after the first image surface of the theodolite traveled through two dialyte lens and then was imaged on CCD. The distance between two spots when exactly focused was set as the calibration value  and the relationship between defocus distance and spot offset was given. The influence of tracking center shift and divergence angle etc. on focusing accuracy was analyzed. Compared with the traditional focusing method  this scheme has a higher accuracy  faster calculation  higher tolerance for environment temperature and a simpler construction. The experiment result exhibited a resolution higher than 0.056mm  which shows a bright engineering application prospect for this method. 2009 SPIE.
