00925njm 22002777a 4500 dc Quiroga Mellado, Juan Antonio author Villa, J. author Gómez Pedrero, José Antonio author 2002-04-01 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. 0030-4018 10.1016/S0030-4018(02)01207-5 https://hdl.handle.net/20.500.14352/58780 http://dx.doi.org/10.1016/S0030-4018(02)01207-5 http://www.sciencedirect.com/ Synchronous detection technique for temporal fringe pattern analysis
