In 1821, Fourier claimed (see Joseph Fourier § The Analytic Theory of Heat) that any function, whether continuous or discontinuous, can be expanded into a series of sines. That important work was corrected and expanded upon by others to provide the foundation for the various forms of the Fourier transform used since. In general, the coefficients are complex numbers, which have two equivalent forms (see Euler's f… WebCircular fringe projection profilometry (CFPP), as a branch of carrier fringe projection profilometry, has attracted research interest in recent years. Circular fringe Fourier transform profilometry (CFFTP) has been used to measure out-of-plane objects quickly because the absolute phase can be obtained by employing fewer fringes. However, the …

WebThis study addresses the effects of a discontinuous test phasor in a single-frequency discrete Fourier transform and the resulting systematic errors in signal and network analysis.
