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.

When a probe laser beam is split and sent through the ... By measuring the differential phase velocity between the two arms of the interferometer, GALILEO can detect the frequency of oscillation ...

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 ...

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 ...
