In this day of digitalization, you can work within the technology of optics without having to
fully understand the science behind it. However, for those who wish to master the science …

We present a new digital two-step reconstruction method for off-axis holograms recorded on
a CCD camera. First, we retrieve the complex object wave in the acquisition plane from the …

This paper provides an overview of recent developments and applications of high-speed
electronic speckle pattern interferometry (ESPI) and related techniques ranging from high …

Various levels of random noise have been added to simulated digital images of a spherical
dome illuminated by fringes projected from an offset angle. The noisy images have then …

This paper presents a new approach to fringe pattern profilometry. In this paper, a
generalized model describing the relationship between the projected fringe pattern and the …

We present an algorithm for estimating the color demixing matrix based on the color fringe
patterns captured from the reference plane or the surface of the object. The advantage of this …

In this paper, we present a mathematical model that describes a general relationship
between the projected signal and the deformed signal in fringe pattern profilometry (FPP) …

Regularized filters (RFs) are used in profilometry for the measurement of three-dimensional
object shapes. A linear grating pattern projected onto an object is phase-modulated by the 3 …

In this paper, a temporal shift unwrapping technique is presented for solving the problem of
shift wrapping associated with spatial shift estimation (SSE)-based fringe pattern …

In this paper, an improved method for three-step phase shifting profilometry (PSP) is
presented to eliminate the errors introduced by the second order harmonic when digital …
