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 ...

Published in Astronomy & Astrophysics, two new studies present an in-depth analysis of the planet Beta Pictoris b's atmosphere using interferometry with the Very Large Telescope ...

It is useful for expanding the effective aperture of the interferometer, in one axis. The measurement area is around the same size as the beam when a laser interferometer's round measurement beam ...

When Hanbury Brown and Twiss (HBT) first proposed that intensity fluctuations of light measured at two different locations carry information on the size of the light source, they met with strong ...

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 ...

The Event Horizon Telescope has accomplished what no other telescope or telescope array has ever done: imaged the event horizon of a black hole directly. A team of more than 200 scientists using data ...
