As being the basic testing and calibration equipment  the large aperture collimator's accuracy should be much higher than the device under testing in order to ensure the accuracy of the measurement. However  the process of adjusting the collimator is extremely complicated due to the collimator's large aperture and long focal length. So it is difficult to ensure the measurement's quality and easy to cause the system being vulnerable to the surrounding environment. One of the most common problems is defocus. In order to solve the problem above  this issue presents a new type of autocollimator autofocusing system which uses pentaprism instead of using large-aperture plane mirror  semiconductor lasers as light source and CCD sensor as receiver. The system is smaller  lighter  and more convenient when using. The computer simulation shows that the autofocusing system's resolution could reach the accuracy of 40m. If we use the relevant algorithms to execute the sub-pixel scanning  the resolution could reach the accuracy of 10m. It shows that the system could satisfy the required testing precision of testing large aperture optical device.   simulation of ingan/gan light-emitting diodes with patterned sapphire substrate 会议论文  OAI收割 12th International Conference on Numerical Simulation of Optoelectronic Devices, NUSOD 2012, Shanghai, China, August 28, 2012 - August 31, 2012 Sheng Yang; Xia Chang Sheng; Simon Li Z.M.; Cheng Li Wen   |  收藏  |  浏览/下载：13/0  |  提交时间：2013/09/22 Computer simulation  Efficiency  Extraction  Finite difference time domain method  Gallium nitride  Optoelectronic devices  Sapphire  Semiconductor quantum wells  Three dimensional computer graphics  Time domain analysis
