长期以来,激光已被用于大范围的精密扫描,譬如用于记录地球资源卫星上传感器的输出。在卫星照像领域内,人们也曾研制过以激光技术为基础的各种光栅扫描和机电测绘装置。过去几年中,制造商为了扩大市场也一直在开发其他的一些应用领域,如制图技术、地震探测的研究、印刷线路板的制作等。这些领域为立足于卫星照像领域的制造商展示出美好的前景。 For a long time, lasers have been used for a wide range of precision scans, such as recording the output of sensors on Earth’s resources satellites. In the field of satellite photography, various types of raster scanning and electromechanical mapping devices based on laser technology have also been developed. In the past few years, manufacturers have been developing other applications to expand the market, such as mapping technology, seismic exploration research, printed circuit board production. These areas present promising prospects for manufacturers based in the field of satellite photography.
