We propose a demodulation algorithm based on the calculus of the complex Fourier coefficients; we used a dual rotating polarizer-analyzer polarimeter to show the feasibility of our proposal. Our demodulation algorithm considers the frequency response

We present a demodulation approach for a rotating polarizer-analyzer polarimeter dedicated to retardance measurements. Through the Mueller matrix approach and the theoretical Fourier transform, we developed a demodulation algorithm considering the tw

We propose a polarizing Michelson interferometer coupled to a pixelated polarizing camera to visualize dynamic phase objects. Considering the capabilities of the polarizing camera, we employed a temporal phase unwrapping algorithm to process informat

We developed simultaneous phase-shifting system based on a Mach–Zehnder interferometer and a replicating system integrated by a Michelson configuration and a cube beam splitter. The system is capable to obtain four simultaneous interferograms in a

We propose to use the fast Fourier transformation (FFT) to analyze the spectral data of passively mode-locked fiber lasers, with the purpose of characterizing and classifying the different pulsed regimes arising in these lasers. The results show temp

In this work, we proposed the usage of a rotating polarizer-analyzer polarimeter to retrieve retardance parameters of a sample by treating it as an elliptical retarder that can be characterized by three parameters: total retardance, fast axis orienta
