本文探讨了遥感图象的频谱分析与多光谱扫描的联合装置方案。由联合装置向地面同时传输多光谱扫描图象和遥感图象的频谱信息。这样可大大提高遥感探测的效率和准确度。本文认为除了电荷耦合器件(CCD)外,还可采用能重复使用、灵敏度和分辨率高的光导热塑胶片作为记录介质。用夫琅和费衍射理论讨论了该种记录介质作为位相方法记录光学成象问题。用相干光照明,获得了位相记录在透射光中在象平面上强度分布的一般表达式。文中比较了几种联合装置方案。第一种方案用CCD作为地物象的探测器。它包括地物的成象系统、CCD记录仪器、结构频谱分析、将电信号传输至地面的装置。第二种方案是
This article discusses the remote sensing image spectrum analysis and multispectral scanning device combination scheme. Spectrum information of multispectral scanning images and remote sensing images is simultaneously transmitted by the joint device to the ground. This greatly increases the efficiency and accuracy of remote sensing. This paper argues that in addition to charge coupled devices (CCDs), photoconductive thermoforms that can be reused, with high sensitivity and resolution, can be used as recording media. Using the Fraunhofer diffraction theory, this recording medium is discussed as a phase method for recording optical imaging problems. Illumination with coherent light gives the general expression of the phase distribution of the intensity distribution in the image plane in transmitted light. The paper compares several joint device programs. The first program uses a CCD as the detector of the image. It includes the imaging system of features, CCD recording instruments, structural spectrum analysis, and devices that transmit electrical signals to the surface. The second option is
