Synthetic Aperture Radar (SAR) interferometry is a remote sensing technique that exploits the phase difference between successive radar images to construct high-resolution topographic maps and monitor ...

This article outlines how to measure, control, and stabilize the relative distance of two interferometer paths to sub-wavelength precision over numerous wavelengths, using the Zurich Instruments MFLI ...

Schematics of the experimental setup for Gouy phase interferometer. The schematic of the experimental setup is shown in figure 1. There are two moveable molecular jets separated in space near the ...

Fringe conference can be traced to the automatic processing of fringe patterns. The term “patterns” evokes an image of flowing lines elegantly wrapped around surface contours. However, automatic ...

For well over 70 years explorers have used seismic survey techniques and seismic wave amplitude interpretation to discover oil and gas. In that time they have relied solely on the measurement of ...

One of the biggest challenges for nanoscale fabrication is how to measure devices on such a minute scale. As the semiconductor industry demands ever smaller devices, the need for reliable, robust ...
