Noise reduction, error analysis and experimental fiability for 3D deformation measurement with digital color holography

摘要

This article presents an analysis of phase errors generated by advanced noise removal algorithms applied to phase maps obtained from digital holographic interferometry. The phase error is separated into two contributions that are the error generated by the denoising method and the error due to the phase noise. A comparison of several noise removal algorithms is presented according to four criteria to assess independently the two types of errors from simulated data. Application to 3D displacement fields measurement of composite material is presented.
