Digital holography enables quantitative phase imaging based on interference. A digital
hologram often encodes the phase information along with aberrations or deformations. This …

Over the past two decades, laser beam melting has emerged as the leading metal additive
manufacturing process for producing small-and medium-size structures. However, a key …

The conical shape of the tympanic membrane (TM or eardrum) plays an important role in its
function, such that variations in shape alter the acoustically induced motions of the TM. We …

Measurement systems for online nondestructive full-field three-dimensional (3D)
displacement based on the single-shot and multiplexing techniques attract more and more …

This paper presents analytical modelling for describing the speckle noise decorrelation in
phase data from two-or multiple-wavelength digital holography. A novel expression for the …

An off-axis digital holographic interferometry technique integrated with a Mach–Zehnder
interferometer based setup is demonstrated for measuring the temperature and temperature …

We present a quasi-common-path interferometer with a double field of view (FOV). The laser
beam of an imaging system is separated into three parts using three mirrors; the first and …

The objective of this paper is to describe a full-field deformation measurement method
based on 3D speckle displacements. The deformation is evaluated from the slope of the …

Testing process in industrial profiling depends on the characterization of three-dimensional
(3-D) objects with high sensitivity in spatial and temporal domains. Ordinary 3-D …

We present a novel single-shot four-wavelength quantitative phase microscopy (FW-QPM).
Four lasers operating at different wavelengths are multiplexed with a pair of dichroic mirrors …
