激光全息干涉检测技术是无损检验、实验力学、工程结构分析及流体特性研究等领域中的一种先进检测手段。随着航天、航空、电子、能源、交通及超重型、超微型工业技术的迅速发展,激光全息技术的应用也越来越广。目前激光全息技术已经跨出实验室阶段,进入到工程实际的应用阶段。传统的连续波激光全息照相对试验环境的稳定性要求十分严格,从而只能限制在实验室中的隔振台上进行试验,若用全息照相法分析现场地面上的工程结构特性,必须采用大能量的脉冲激光器,这种
Laser holographic interference detection technology is non-destructive testing, experimental mechanics, engineering structural analysis and fluid properties in areas such as an advanced detection methods. With the rapid development of aerospace, aviation, electronics, energy, transportation, ultra-heavy and ultra-miniature industrial technologies, the application of laser holography has become more and more widespread. The current holographic laser technology has taken the laboratory stage, into the engineering application stage. The traditional continuous wave laser holography is very strict on the stability of the test environment, which can only be limited to the vibration isolation test in the laboratory test. If holographic method is used to analyze the structural characteristics of the site on the ground, we must use large Energy pulsed lasers, this
