The generalized principle of moiré interferometry is explained theoretically. As a result it becomes clear that the application of incoherent moiré techniques to a two-beam interferometer enables measurement of wavefront deformation that is given by an object at two different times, but it cannot reduce distortion in a viewing system.

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 samples, for which the interference fringes have the shape of spirals instead of closed contour lines as in traditional interferograms.

Laser feedback interferometry: a tutorial on the self-mixing effect for coherent sensing
, 2015This tutorial presents a guided tour of laser feedback interferometry, from its origin and early development through its implementation to a slew of sensing applications, including displacement, distance, velocity, flow, refractive index, and laser ...

The use of a two-frequency, Zeeman effect laser permits simple, stable, rapid, and highly accurate interferometry. There are a number of interesting applications. Three if them are discussed here.

Asteroseismology & Interferometry
2005Asteroseismology aims at constraining the stellar evolution theory, and allows to determine the age of stars together with other fundamental parameters. We present recent results obtained by interferometry, and prospects for the future.
