Advances in quantum technology might allow astronomers to circumvent age-old issues that limit the size of optical observatories ...
Large-scale atom interferometers, analogous to optical interferometers but measuring the difference in phase between atomic matter waves on different paths, are intended to be key elements in future ...
A new concept has been developed that has the potential to assist new instruments in the investigation of fundamental science topics such as gravitational waves and dark matter. A new concept has been ...
Ground-based interferometry on Earth has proven to be a successful method for conducting science by combining light from several telescopes into acting like a single large telescope. But how can an ...
In optical astronomy, the highest angular resolution is presently offered by phase/amplitude interferometers combining light from telescopes separated by baselines up to a few hundred metres.
In 1920–21, scientists Albert Michelson and Francis Pease measured the first stellar diameter, of Betelgeuse, at the Mount Wilson Observatory. Today we refer to the technique they used as ...
When it comes to telescopes, many would argue that bigger is better. During the 20th Century, astronomers and engineers built telescopes with larger and larger apertures, striving to gather more and ...
The fiber itself is used as a transducer in many fiber optic sensing systems (see the section titled “Fiber Sensors,” in ADVANCES IN OPTICAL METROLOGY, the section titled “Optical Fiber Sensors,” in ...
When designing materials and structures at the nanoscale, it is important to be able to characterize and measure them. Getting tools to measure on these very small length scales can be challenging as ...
