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 ...

X-ray imaging commonly relies on the attenuation contrast, in which the visibility of internal structures arises from different levels of radiation absorption. In comparison, phase-contrast imaging, ...

NASA NIAC willl investigate the details of building a high-resolution, long-baseline, optical imaging interferometer on the lunar surface in conjunction with the Artemis Program. A lunar ...

ABSTRACT.The Murchison Wide-Field Array (MWA) is a low-frequency radio telescope, currently under construction, intended to search for the spectral signature of the epoch of reionization (EOR) and to ...

The Magdalena Ridge Observatory Interferometer (MROI) project’s mission is to develop a ten-element imaging interferometer to operate at wavelengths between 0.6 and 2.4 microns with baselines from 7.8 ...

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 ...

In a study published in Nature Methods on December 2, a research team led by Profs. Xu Tao and Ji Wei from the Institute of ...

A new imaging technology developed at the University of Connecticut promises to rewrite the rules of optical imaging, ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

Imagery of objects in low Earth orbit (LEO) (left) can achieve much higher resolution than images of objects in geosynchronous Earth orbit (GEO) (right), which appear only as rough blobs. To improve ...
