检测技术在国民经济的各个行业中,起着举足轻重的作用,无论科学研究、产品质量及自动控制都需要检测,利用现代光电子技术作为检测手段,具有无接触、无损、远距离、抗干扰能力强、受环境影响小、检测速度快、测量精度高等优越性,是当今检测技术发展的主要方向。利用光的干涉、衍
Detection technology plays an important role in all sectors of the national economy. Whether in scientific research, product quality and automatic control need to be detected, the use of modern optoelectronic technology as a detection means, with non-contact, non-destructive, long-distance, anti-interference ability , By the environmental impact of small, fast detection, measurement accuracy and superiority, is the main direction of development of detection technology today. The use of light interference, Yan
