A novel phase extraction method for fringe patterns with carrier frequency and with slow variation with time is presented. It is based on the Fourier-transform method and on the quotient of the two adjacent frame fringe patterns. The fringe patterns are obtained by fringe projection on a fixed end o
Hough Transform for the Parametrisation of Straight Lines using Fourier Methods T he Hough transform is a useful technique in the detection of straight lines and curves in an image. Due to the mathematical similarity of the Hough transform and the forward Radon transform, the Hough transform can be
Use of high resolution Fourier transform spectroscopy has allowed the study of the Doppler shifts of 4p Ar + emission lines found in Ar + lasers, as a function of polarity and pressure of a At/He discharge. The results indicate that the emitting 4p states can be distinctly divided into low and high
