光学测量位移传感器全世界各种装置和机械生产的迅速演进及其爆炸性计算机化正导致测量技术和信号变换装置迅猛发展。例如，美国１９８６～８７年用于测量的年总费用约为２００亿美元，其中用于航天、国防技术、光电子、微电子和生物技术的测量费用约为普通机床业的３倍［...
Optical Measurement Displacement Sensors The rapid evolution of explosive devices and mechanical production worldwide and their explosive computerization are leading to the rapid development of measurement technology and signal conversion devices. For example, the total annual cost for the United States from 1986 to 1987 was about 20 billion U.S. dollars, of which the cost for aerospace, defense technology, optoelectronics, microelectronics and biotechnology was about three times that of the conventional machine tool industry.
