    This document explains how to read the RADARSAT data CD provided with the book "Digital Processing of Synthetic aperture Data" by Ian Cumming and Frank Wong, Artech House, 2005. On this web site, programs are provided in MATLAB to read the data and parameters from the CD. The structure of the programs is outlined in Figure 1. There are two main programs and one function that are used to extract

  • VCSELs and EELs

    InGaAs/AlGaAs semiconductor lasers come in threetypes: VCSELs and two types of EELs. The VCSEL, asits name implies, emits vertically, normal to the planeof the device, owing to cavity mirrors grown withinthe epitaxial material itself. The VCSEL’s circular beamhas a numerical aperture (NA) of roughly 0.2, or a fullangle of approximately 25 degrees.

  • ZEMAX入门教学实例

    1-1单透镜这个例子是学习如何在ZEMAX里键入资料,包括设置系统孔径(System aperture)、透镜单位(Lens Units)、以及波长范围(Wavelength Range),并且进行优化。你也将使用到光线扇形图(Ray Fan Plots)、弥散斑(Spot Diagrams)以及其它的分析工具来评估系统性能。这例子是一个焦距100mm、F/4的单透镜镜头,材料为BK7,并且使用轴上(On-Axis)的可见光进行分析。首先在运行系统中开启ZEMAX,默认的编辑视窗为透镜资料编辑器(Lens Data Editor,LDE),在LDE可键入大多数的透镜参数,这些设置的参数包括:·表面类型(Surf:Type)如标准球面、非球面、衍射光栅..等·曲率半径(Radius of Curvature)·表面厚度(Thickness):与下一个表面之间的距离·材料类型(Glass)如玻璃、空气、塑胶.…等:与下一个表面之间的材料
