Abstract

An electronic speckle pattern interferometry (ESPI) system for detection of cracks and defects is presented. In the first stage a holographic optical element (HOE) is recorded using a photopolymer material. Since the polymerisation process occurs during recording, the holograms are produced without any development/processing. In the second stage the HOE is used in an ESPI configuration for detection of cracks and defects. Due to the introduction of the HOE in the ESPI set-up, precise alignment of the optical elements is not necessary. For this reason the system is well suited for industrial applications.
