在我院与中国计量科学研究院共同研制的国内第一台“双频激光干涉仪”的基础上,我院精密仪器工程系又应用微机,研制成功我国第一台“微电脑双频激光干涉仪”。该仪器不仅显著提高了双频激光干涉仪的稳定性,而且软件硬件相结合扩展了多项功能,对环境条件和工件参数可进行修正。仪器在机械工业部东方电机厂运行考查半年,性能稳定可靠,有较 On the basis of the first dual-frequency laser interferometer developed in our institute and China Institute of Metrology, the Precision Instrument Engineering Department of our institute has also developed the first “Microcomputer Dual-frequency Laser Interferometer ”. The instrument not only significantly improves the stability of the dual-frequency laser interferometer, but also integrates software and hardware to extend a number of functions and corrects environmental conditions and workpiece parameters. Instrument in the Ministry of Machinery Industry Dongfang Electrical Plant operation test six months, stable and reliable performance, more
