摘　　要：电子散斑干涉技术是一种测量物体表面微小形变的非接触式测量技术。它是在激光、视频、电子及数字图像处理等基础上发展起来的现代光测技术,具有高精度、全场、实时测量等特点,有着重要的理论研究和实用价值。介绍电子散斑干涉技术的基本原理和特点以及在无损检测领域最新研究进展,并探讨了未来的发展趋势。Based on modern high technologies such as laser, video, electronics, image processing and holography, ESP1（Electronie Speckle Pattern Interferometry） is a non-contact measuring method, which can measure the small static and dynamitic surface deformations and reveal flaws by looking for flaw-induced deformation anomalies. With the advantages of high precision, high sensitivity, wide frequency bandwidth and full-field real-time testing, it has a promising future in engineering. Its basic theory and recent applications in nondestructive testing are reviewed. Finally, its scope for improvement is discussed.
