Quantitative phase microscopy (QPM), a technique combining phase imaging and
microscopy, enables visualization of the 3D topography in reflective samples, as well as the …

Shack–Hartmann wavefront sensors measure the local slopes of an incoming wavefront
based on the displacement of focal spots created by a lenslet array, serving as key …

This Letter presents the τ interferometer, a portable and inexpensive device for obtaining
spatial interferograms of microscopic biological samples without the strict stability and the …

The word 'holography'means a drawing that contains all of the information for light—both
amplitude and wavefront. However, because of the insufficient bandwidth of current …

We show that phase objects may be computed accurately from a single color image in a
brightfield microscope, with no hardware modification. Our technique uses the chromatic …

A simple and cost-effective method is presented for quantitative phase imaging. A common-
path lateral phase shifting interferometer is realized through attaching a compact filter set to …

Phase imaging microscopy under Gabor regime has been recently reported as an extremely
simple, low cost and compact way to update a standard bright-field microscope with …

Slightly off-axis digital holographic microscopy (SO-DHM) has recently emerged as a novel
experimental arrangement for quantitative phase imaging (QPI). It offers improved …

Phase-imaging techniques extract the optical path length information of a scene, whereas
wavefront sensors provide the shape of an optical wavefront. Since these two applications …

Differential image contrast (DIC), through the numerical managing and manipulation of
complex wavefronts obtained by digital holography (DH), is investigated. We name the …
