Fractional Fourier transform method of chirped fringe pattern analysis for profilometry

A method is proposed to obtain the 3D profile of an object or the shape of a wavefront. The analysis of linearly chirped cosenoidal fringes is performed in the fractional Fourier domain. © OSA 2020, © 2020 The Author(s)
