摘　　要：激光多普勒测速法是一种高精度测速的方法,在测量流体速度方面应用较广,但因测速仪器技术含量高,目前主要靠进口欧美国家的产品,因而成本较高,在电缆、钢材行业应用有限,文章就是欲将激光多普勒测速法向电缆行业推广的一次尝试,对改善我国电缆行业长期存在的定长精度不能达到国际标准、浪费现象严重的现状具有一定的意义。Laser Doppler Velocity measurement is a high accuracy measuring method of velocity, and is widely applied to flow rate measurement. Because cost of this instrument is expensive, it is applied hardly in cable and steel industries, this thesis tries to popularize laser doppler velocity measurement to the field of cable industry to improre long-standing condition of cable industry in our country that length measuring accuracy can not attain the international standard and waste is serious.

关 键 词：激光多普勒测速法 电缆动态定长 计数型信号处理法
