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.   Temperature characteristics of several familiar diode lasers with broad area (EI CONFERENCE) 会议论文  OAI收割 Optoelectronic Materials and Devices III, October 27, 2008 - October 30, 2008, Hangzhou, China 作者:  Wang L.;  Qin L.;  Wang L.;  Wang L. 收藏  |  浏览/下载：25/0  |  提交时间：2013/03/25 Temperature characteristics of several familiar high power diode lasers with broad area  whose wavelength was separately 808 nm  810 nm  940 nm and 980 nm  were analyzed. In order to see the effect the change of the quantum well structure on the characteristic temperatures  different structures were attempted. For the 808 nm structure  we tried different barrier thicknesses. For the 810 nm structure  different cavity lengths were attempted. And we studied the 940 nm and 980 nm also. In this paper  the widths of these devices were all 100 m. Characteristic temperatures of these devices were calculated. The appropriate structure was available for different application. 2008 SPIE.
