Nettet12. apr. 2024 · The interferometer produces an equidistant and straight fringe pattern (Young’s fringes; fringe interference field) that is recorded by the detector array and processed by a computer, yielding retardation. An accuracy of 2π/2100 rad was demonstrated in [ 36 ], with a resolution from 2π/4000 rad [ 36] to 2π/1000 rad [ 34 ].
Photonics Integrated Interferometric System Simplifies High …
Interferometers and interferometric techniques may be categorized by a variety of criteria: In homodyne detection, the interference occurs between two beams at the same wavelength (or carrier frequency). The phase difference between the two beams results in a change in the intensity of the light on the detector. The resulting in… NettetDescription : GouMax’s high-speed wavelength meter (WLM) is designed for applications to test and measurement equipment.
