Abstract

This paper provides an overview of the current state-of-the-art in fringe pattern analysis, with a particular emphasis on recent developments in digital speckle pattern interferometry (DSPI) and digital speckle photography (DSP). The main topics covered are as follows: spiral transform for analysis of fringe patterns without spatial carriers, real-time analysis, dynamic DSPI, three-dimensional phase unwrapping, combined DSPI/DSP techniques, and three-dimensional DSP. Several interesting applications outside mainstream speckle metrology are also described, including fingerprint analysis, and measurement of both strain and magnetic fields within the human brain using phase contrast magnetic resonance imaging (MRI).
