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 w insta saree fringes.The objective of this work is to apply an optimizer block that feeds from the first stages of the FSD and make feedback in such a manner as to optimize the search for guided frequencies.This approach significantly reduces demodulation errors, especially when dealing with high-frequency fringe patterns.

The results of using the FSD with and without optimizers are compared.The optimizers used are the Harmonic Search Optimization (HSO) as well as the Particle Swarm Optimization (PSO).Results show that FSD with PSO delivers better hubbell 5362w results compared with other methods here analyzed.
