Micro-temperature variation and temperature gradients not only cause the change of the air refractive index and lead to the optical path variation in interferometer cavity  but also result in deformation of the tested surface itself  which always brings about errors to the test results. Temperature effects on the interferometer cavity and the tested surface are analyzed from the axial and radial directions in this letter. Temperature model of the interferometer cavity and the tested lens are established and quantitative calculations and diagram of test results versus temperature and lens dimension are provided. It shows that temperature gradients effect increase with the length of the interferometer and the dimension of the tested lens. The interferometer cavity is mainly affected by radial temperature gradients while the tested lens is mainly affected by the axial temperature gradients. 2010 Copyright SPIE - The International Society for Optical Engineering.   Space camera focusing forecast based on RBF network (EI CONFERENCE) 会议论文  OAI收割 Computational Intelligence and Intelligent Systems: 4th International Symposium, ISICA 2009, Huangshi, China, October 23-25, 2009. Proceedings, Tiergartenstrasse 17, Heidelberg, D-69121, Germany 作者:  Liu J.;  Yu D.;  Yu D.;  Liu J.;  Liu J. 收藏  |  浏览/下载：24/0  |  提交时间：2013/03/25 As circumstance temperature of space camera changes  flex of structural components and distortion of optical components lead to change of focal length and image quality. Radial Basis Function (RBF) network is used to approximate the complex nonlinear relation between focalization quantity  image quality  temperature level and axial temperature difference of space camera. After the RBF Network is trained with thermo-optical experiment data  temperature level and axial temperature difference could be input to the network to obtain colder value of best image position. In this way focusing forecast under different temperatures can be realized. Results of focusing forecast experiment validate this method. 2009 Springer-Verlag Berlin Heidelberg.
