RT Journal Article T1 Synchronous detection technique for temporal fringe pattern analysis A1 Quiroga Mellado, Juan Antonio A1 Villa, J. A1 Gómez Pedrero, José Antonio AB An alternative method for temporal evaluation of fringe patterns is proposed. The method is based on the application of a synchronous detection system for processing the temporal irradiance fluctuations generated when the sensitivity of the optical set-up is changed. The technique requires an easy computing implementation and presents good noise rejection characteristics, In particular, the proposed method does not require to store the whole set of fringe images as it happens with Fourier techniques which allows for a faster data processing. Results of this method proved on synthetic fringe images as well as in real experiments are presented.
