摘要
引入了一种新的无损检测技术—激光散斑无损检测技术。文中首先阐述了激光散斑检测的原理和主要技术参数。着重研究了激光散斑检测技术,并将散斑照相和激光全息照相进行了比较分析。这一先进的光测技术与传统的检测方法相比有不可比拟的优越性,是一种先进和具有发展潜力的光测技术。
One kind of new nondestructive testing （NDT） technology-laser shearography was led in this article. Principle that the laser shearography and major technology parameter were firstly expounded. Stresses studying laser shearography technology, and carry on the comparison analysis with laser shearography and holography. This advanced flash ranging technology is compared the superiority cannot compare with the testing method of tradition, and is one kind of flash ranging technology of advanced and possesses development htent capacity.
