TL;DR: In this paper, a horizontal circular cylinder is moved vertically and also horizontally at constant velocity normal to its axis in density stratified brine which has a constant buoyancy frequency, N. The Reynolds numbers based on the cylinder diameter, D, are between 1 and 10 and the frequency parameter, DN/U, where U is the body velocity, is of order one.
Abstract: Experiments are described in which a horizontal circular cylinder is moved vertically and also horizontally at constant velocity normal to its axis in density stratified brine which has a constant buoyancy frequency, N. A six mirror Mach Zehnder interferometer is used to measure the density distributions within the far field wave systems. The Reynolds numbers based on the cylinder diameter, D, are between 1 and 10 and the frequency parameter, DN/U, where U is the body velocity, is of order one.

TL;DR: In this paper, a symmetrical six-mirror interferometer was proposed for density stratified liquids. But it is inconvenient for the study of density stratification because of the refractive index gradient in the undisturbed state.
Abstract: The conventional four-mirror interferometer is inconvenient for the study of density stratified liquids because of the refractive index gradient in the undisturbed state. It is found that a symmetrical six-mirror system is ideal for stratified liquids. The paths of the light rays through the system are analysed and experiments are described which verify that accurate quantitative results can be obtained.

TL;DR: In this paper, it was shown that when the Marangoni number is increased beyond a critical value, a series of oscillatory modes develop in the vicinity of the bubble, and the oscillations have been detected in both the basic flow induced by combined MARG and buoyancy effects, by using a laser sheet for tracing particles, and in the temperature field visualized by interferometry techniques.
Abstract: In space and many industrial cases on earth which involve materials processing, manufacturing, and storage and management of liquids, the interaction between gas and vapor bubbles with the surrounding is of great interest. Study of therrnocapillary motions near bubbles attached to a heated or cooled wall in conjunction with the space experiments has received considerable attention in recent years. We present results of preliminary experimental observations which have indicated that when the Marangoni number is increased beyond a critical value, a series of oscillatory modes develop in the vicinity of the bubble. The oscillations have been detected in both the basic flow induced by combined Marangoni and buoyancy effects, by using a laser sheet for tracing particles, and in the temperature field visualized by interferometry techniques. The influence of the Marangoni and Prandtl numbers and bubble geometry on the oscillations are indicated.

TL;DR: In this article, a dual-path Mach-Zehnder interferometer is used to measure the geometric phase introduced by polarization optics composed of retarders, which can be used either to determine a polarization state of light or measure the Jones matrix of retarder and polarization elements.
Abstract: We present a polarimetry method based on measurement of the geometric phase. We implement a dual-path Mach-Zehnder interferometer to measure the geometric phase introduced by polarization optics composed of retarders. The method can be used either to determine a polarization state of light or to measure the Jones matrix of retarders and polarization elements.
