我系于1985年研制成功的微电脑双频激光干涉仪,已达到当时的国际先进水平。在此基础上,于1986年开始研制五米激光测长机,经过三年的努力,于1989年研制成功,经过半年的运行考核,基本达到预定的目标。1989年9月对该机进行了鉴定。这台测长机利用双频激光干涉仪测长和光电显微镜瞄准,集激光技术、光电技术、计算
I was successfully developed in 1985 microcomputer dual-frequency laser interferometer, has reached the international advanced level. On this basis, we started to develop the five-meter laser length measuring machine in 1986, and after three years of hard work, it was successfully developed in 1989. After six months of operational evaluation, we basically achieved the scheduled target. September 1989 on the aircraft were identified. This length measuring machine using dual-frequency laser interferometer length and light microscope aiming, set of laser technology, optoelectronic technology, computing
