In a traditional laser interferometer, light from a laser source is split into two beams ... the amplitude of the test beam and the phase difference between the two interfering beams.

Skip to content viewer section. ABSTRACT.As part of the astrometric and phase-referenced astronomy (ASTRA) project, three new science modes are being developed for the Keck Interferometer that extend ...

In an atom interferometer, lasers split a wave-like atom into two waves, send those waves on two different paths and then recombine them. When the waves recombine, they create a pattern ...

A source beam is collimated in a Twyman-Green laser interferometer and subsequently split by a beam splitter ... This interference pattern is caused by changes in phase that, in turn, is induced by ...
