title: Circular fringe carrier technique in holographic interferometry.
abstract: An improved fringe carrier technique can eliminate the ambiguity in holographic fringe interpretation. This paper presents a new fringe carrier technique-a circular fringe carrier technique that not only eliminates the ambiguity in holographic fringe interpretation but also determines the direction of displacements and obtains the required fringe spacings without precisely adjusting the object beam.
