Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies ...

This paper describes the measurement of additive/residual phase noise of power amplifiers or multipliers for automotive radar sensors at 80 GHz using the interferometric measurement approach in ...

Because of the high vertical and lateral resolution and the speed of measurement, vertical scanning interferometry is ideal for these studies. The capability of measuring these changes in a ...

The camera was first developed for use in laser interferometry, a technique for measuring physical parameters such as the wave-front quality of optics and the shape of optical-grade surfaces.

Image Credit: 4D Technology. Phase shifting interferometry integrates a number of data frames to quantify the heights of all points present on the test surface to precisely measure the shape of the ...

Based on the slope and frequency of the surface characteristics, traditional interferometer systems – which are well-matched for measuring surface form – are incapable of measuring and quantifying ...

Today, the Awards Committee of SPIE, the international society for optics and photonics, announced the recipients of its ...
