We have developed a line-scanning interferometric microscope capable of measuring the
quantitative phase over a wide continuous spectrum. The sample is illuminated with a …

In any microscope, the formation of an image depends on the interference of light: according
to Abbe's theory, the image results from the interference of direct and diffracted light in the …

We present a new interference microscope for quantitative measurement of transparent
objects. High precision measurement is achieved by applying the phase-shifting …

An AC interference microscope based on a technique called phase-locked interferometry
has been constructed. The instrument is capable of detecting phase differences …

We present a surprising modification of optical interferometry. A so-called spiral phase
element in the beam path of a standard microscope results in an interferogram of phase …

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 …

A quantitative phase microscope is demonstrated using spectrally-encoded interferometric
phase modulation. The technique offers speckle-free, high sensitivity (~ 0.14 nm) optical …

We present a compact, highly portable and inexpensive interferometric module for obtaining
spatial interferograms of microscopic biological samples, without the strict stability and the …

We developed a new quantitative phase microscopy technique, namely, spectrally resolved
laser interference microscopy (SR-LIM), with which it is possible to quantify multi-spectral …

We show by analytical and numerical calculations that the phase change on reflection that
occurs in interference microscopy is almost independent of the numerical aperture of the …
