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 ...

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 ...

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 ...

In this interview, Dr. Erik Novak, from 4D Technology TM, talks to AZoM about 4D dynamic interferometry. To begin, can you give us an introduction to what dynamic interferometry is and how it can be ...

Measuring high aspect ratio and composite micro-trenches without damage is critical for advanced microfabrication, yet conventional coherence scanning interferometry often suffers from a low signal-to ...

The nature of quantum particles has long puzzled scientists. While single-particle interference suggests that a photon can behave like a spread-out wave, a whole photon is only ever detected in one ...

Manufacturing a precision surface requires a balance between satisfying the optimum quality requirements at the minimum cost. Steve Martinek summarizes the challenges of increasing the precision ...
