摘要
Electronic speckle pattern interferometry (ESPI), pioneered 30 years ago, represents one of the most powerful tools for industrial nondestructive testing and metrology. Main advantages include speed of data acquisition and processing, relative simplicity and possibility to work outside the laboratory. Steady progress in optoelectronics, fibre technology and informatics facilitates the development of compact and robust systems for new tasks in engineering analysis.
