spot resolution

Landsat Thematic Mapper ( TM) image is rich in spectral information, while SPOT panchromatic data is fine in its spatial resolution. Complementary and effective use of these data has shown in its increasing importance in the field of remote sensing application.

陆地卫星TM图像含有丰富的光谱信息，SPOT全色波段图像数据分辨率较高，因此，如何将这两种图像数据有效地结合起来，在遥感应用领域中显得越来越重要。

Then the diffraction spot size is decreased, and the optical resolution is increased, so the accuracy of the fine tracking system is improved.

由此减小接收衍射光斑的大小，提高系统的光学分辨能力，从而提高精跟踪系统的精确性。

A method of matrix scanning with a high resolution flying spot tube is adopted in the scanner. It has the advantages of high speed and flexible control.

该扫描器采用高分辨率飞点管作阶梯波点阵扫描，具有速度快、控制灵活的优点；
