One of the hardest things to calculate for an asteroid is its mass—but it is such a critical feature. It determines how much ...

Earth's atmosphere is an impediment to astronomical observations. Not only is cloudy weather a problem, but temperature fluctuations in the atmosphere mean that ground-based telescopes require ...

Interferometers are research instruments that are utilized in many disciplines of science and technology. Interferometers are so-called because they function by combining multiple sources of light to ...

Optical interferometry-based techniques are ubiquitous in various measurement, imaging, calibration, metrological, and astronomical applications. Repeatability, simplicity, and reliability of ...

The double-slit experiment and interferometry as a whole are corner-stones of quantum physics. Any coherent system, e.g., light, electrons or the neutrons regarded in this letter, may exhibit ...
