摘要
本文从原理与实验论述了如何应用自动计算全息图的四个干涉图法高精度、非接触、实时地测试被测物体变形的全信息：变形的大小、方向和形状。并用光导热塑料相机和计算机控制的全息装置成功地测定了压力鼓受气压后变形的滞后线。它表明，这种新的自动计算全息图的全息干涉术使全息干涉术从实验室走向工业测试成为可能。
In this article we have theoretically and experimentally discussed,Howcan we high accuracy non一contact real-time n1easure all information(ouantity direction andform) with 4-interferograms method of automatic hologram calculation, With a photocon-ductor thermoplastic camera and holographic setup controlled by a computer we have suc-cessfully for a company measured hysteresis line of a pressure drum under atmospheric pres-sure. Tmsnew ho,.ographic interferornetry with automatic hoogram calculation makkes it pos-sible for holographic interferometry to go from laboratory to industry.
