Interferogram analysis explores the advancements in digital fringe pattern measurement techniques, focusing on the transformative impact of digital methods in interferometry. Interferogram analysis digital fringe pattern measurement techniques edited by david w robinson and graeme t reid institute of physics publishing. In this paper, the demodulation methods of vortex interferograms are first reviewed in terms of intensity, phase and rotating frequency for uniform phase measurement. then, the demodulation method is extended to non uniform phase measurement.
Pdf Diamond Turning Tool Setting By Interferogram Analysis Interferogram analysis digital fringe pattern measurement techniques edited by david w robinson and graeme t reid institute of physics publishing. In this paper, the demodulation methods of vortex interferograms are first reviewed in terms of intensity, phase and rotating frequency for uniform phase measurement. then, the demodulation method is extended to non uniform phase measurement. Recently, spiral phase filtering for isotropic edge enhancement and for optical thickness measurements of phase samples has been implemented in microscopy, using gray value images on a spatial light modulator (slm) placed in a fourier plane of the sample. We investigate the theoretical background of “spiral interferometry” and suggest various demodulation techniques based on the processing of one single interferogram or multiple interferograms. A so called spiral phase element in the beam path of a standard microscope results in an interferogram of phase samples, for which the interference fringes have the shape of spirals instead. We investigate the theoretical background of “spiral interferometry” and suggest various demodulation techniques based on the processing of one single interferogram or multiple interferograms.”.
