With the progress of science and technology, industrial requirements increase, measuring precision about displacement and deformation becomes higher and higher.Measurement accuracy of digital holographic measure technology has easily up to micron level. And it has many advantages, such as full-field, real-time, non-contact, high-contrast. Therefore, it has big trend in the development of holographic interferometry. In this paper, holographic interference measure system based on photosensitive detector,EALCD...
