Frequency-guided sequential demodulation (FSD) is a technique used to recover the phase of closed fringe patterns when only a single interferogram is available. FSD is a sequential method that follows simple and intuitive processing steps for interferogram demodulation. guided by the frequency of the fringes. The objective of this work is to apply an optimizer block that feeds from th... https://www.roneverhart.com/Stoneraven-West-Non-Ladder/
