Its optical system consists of an emitting system  receiving system  and two penta-prisms. Emitting system has three parts: a light source  beamsplitter  and aim slit. The receiving system includes a field lens  two separate lenses  and CCD. Using two little penta-prisms instead of a large planar mirror makes the autofocus system simple and compact. CCD was used as photoelectric converting device. A defocused signal is acquired by measuring the change of the two slit self-images position imaged on the CCD. A simple and compact construction of the auto-focusing system was proposed. The algorithm to calculate the moving of the slit-self images position was analyzed in order to achieve subpixel position estimation. The results of the experiments show a 10m focusing precision. The system demonstrates high resolution  easy adjustment and high reliability.   Difference schemes on non-uniform mesh and their application 期刊论文  OAI收割 Progress in Natural Science, 2004, 卷号: 14, 期号: 10, 页码: 848-854 作者:  Ma YW(马延文);  Gao H(高慧);  Fu DX(傅德薰);  Li XL(李新亮) 收藏  |  浏览/下载：945/51  |  提交时间：2009/08/03 Scheme On Non-Uniform Mesh  High Order Accurate Scheme  Compact Difference Approximation  Simulations
