Advanced carrier squeezing interferometry: a technique to suppress gamma distortion in fringe projection profilometry.

Abstract

An advanced carrier squeezing interferometry (CSI) technique is proposed to suppress gamma distortion in fringe projection profilometry. CSI combines phase-shifted fringes into a single spatial-temporal fringe and then extracts the phase from its frequency spectrum. Although it has the property of rejecting high-order harmonics, the traditional CSI… (More)
