Rayleigh Interferometer for Analysis of Liquids Analytical Chemistry

In optics, a Rayleigh interferometer is a type of interferometer which employs two beams of light from a single source. The two beams are recombined after traversing two optical paths, and the interference pattern after recombination allows the determination of the difference in path lengths. See more Light from a source (left) is collimated by a lens and split into two beams using slits. The beams are sent through two different paths and pass through compensating plates. They are brought to a focus by a second lens … See more The advantage of the Rayleigh interferometer is its simple construction. Its drawbacks are (i) it requires a point or line source of light … See more • List of types of interferometers See more WebDec 18, 2024 · Rayleigh length, z R = 14mm. Due to the Gouy phase, there is a phase difference between carrier wave and envelope of driving laser ﬁeld that turns into π/2 phase shift over a Rayleigh length (±z R). (c) Gouy phase imparts a delay in emission time Δt that results in a phase shift, Dfbetween the two XUV pluses.
