Paper Abstract

A massively parallel real-time algorithm for the estimation the dynamic phase map of a vibrating object is presented. The algorithm implements a Fourier-based quadrature transform and temporal phase unwrapping technique, and was implemented using CUDA, a general purpose computing and development environment for NVIDA GPU's. The algorithm was tested on a 64 × 640 fringe patterns sequence achieving a processing rate higher than 2270 frames per second (fps).
