Fast half-quadratic regularized phase tracking for nonnormalized fringe patterns.
Although one of the simplest and powerful approaches for the demodulation of a single fringe pattern with closed fringes is the regularized phase-tracking (RPT) technique, this technique has two important drawbacks: its sensibility at the fringe-pattern modulation and the time employed in the estimation. We present modifications to the RPT technique that consist of the inclusion of a rough esti...
متن کاملImproving Rtisi Phase Estimation with Energy Order and Phase Unwrapping
This paper presents two ways to improve the Real-Time Iterative Spectrogram Inversion (RTISI) algorithm. The standard RTISI phase estimator with look-ahead processes the buffered frames in reverse order. We show that better results are achieved by controlling this order according to frame energy. Another improvement is to initialize the last row of the phase estimator buffer by progressing the ...
متن کاملA New Algorithm of Phase Unwrapping
Phase unwrapping is one of important task in synthesizes aperture radar (SAR) interferometric measurement data processing procedure. Accuracy of it will directly affects precision of the interferometric measurement result. Through the experimental study, this paper analyzes principle and the characteristic of two kind of main current phases unwrapping algorithm, then conbines respective merit a...
متن کاملRegularized Quadrature and Phase Tracking (rqpt) from a Single Closed- Fringe Interferogram
A new sequential phase demodulator based on a Regularized Quadrature and Phase Tracking system (RQPT) is applied to demodulate two-dimensional fringe patterns. This RQPT system tracks the fringe pattern’s quadrature and phase in a sequential way following the path of the fringes. To make the RQPT system more robust to noise the modulating phase around a small neighborhood is modeled as a plane ...
متن کاملFirst fringe measurements with a phase-tracking stellar interferometer.
A prototype two-telescope stellar interferometer with a 1.5-m base line has been used to track the white-light fringes, 0.4-0.9 microm, from Polaris. Continuous fringe phase and amplitude measurements were made with ~220-photon/4-msec integration time and 1.27-cm(2) collecting area under 2-arc sec seeing conditions. The same control algorithm should be able to track fringes from an 8.7-mg star ...
