目前,我国地震观测手段有不少观测仪器是利用光点感光照相记录,如磁变仪、倾斜仪、以及其他地震仪器等。其工作程序繁杂、人为误差大,不利于观测系统数字化。随着数字处理现代化和自动传输系统在地震部门的应用和发展,光点感光照像记录的方法,已无法再适应科技发展变革的步伐。从五十年代起就有人提出过这个问题,并进行研究,但因受科技条件的制约,未能取得突破性进展。随着光电技术的发展,为解决光电转换奠定了基础。国家地震局分析预报中心师会等同志,经过一年时间的研制,采用目前国际最新技术(CCD
At present, there are many observational instruments in seismic observation in our country that use light-point photographic records, such as magnetometer, inclinometer, and other seismic instruments. Its complicated working procedures, human error, is not conducive to digital observation system. With the application and development of digital processing modernization and automatic transmission systems in the seismological sector, the method of spot-sensitive photographic recording can no longer meet the pace of technological change. Since the 1950s, some people have raised this issue and conducted research. However, due to the restriction of scientific and technological conditions, no breakthrough progress has been made. With the development of optoelectronic technology, laid the foundation for solving photoelectric conversion. National Seismological Bureau Analysis and Prediction Center teachers and other comrades, after a year of research and development, using the latest international technology (CCD
