Application of adaptive TV holography for wide scale displacement measurement

摘要

In our paper we have analysed the application possibilities of a modified version of speckle pattern interferometry: the adaptive TV holography (ATVH). The core of this technique is using holographically reconstructed virtual images of referencewaves. With this solution an adaptive measuring system can be built.A developed prototype of the ATVH is presented as a measuring device for various measuring tasks. Selected applications are shown from real time holography to comparative displacement.
