Holographic Fabry-Perot spectrometer.
We propose a spectrum analyzer based on the properties of a hologram recorded with the field transmitted by a Fabry-Perot etalon. The spectral response of this holographic Fabry-Perot spectrometer (HFPS) is analytically investigated in the paraxial approximation and compared with a conventional Fabry-Perot etalon of similar characteristics. We demonstrate that the resolving power is twice incre...
متن کاملFabry - Perot Interferometer
This short lecture note recalls some of the properties of Fabry-Perot interferome-ters. As an addition to textbooks , it may present some help to students working with such instruments.
متن کاملFabry - Perot Interferometer Prototype
A new Fabry-Perot Interferometer has been developed for the ADAHELI ADvanced Astronomy for HELIophysics solar satellite mission at the “Tor Vergata” University Solar Physics Laboratory. Fabry-Perot narrow filters are of great interest for the study of extended astronomical sources, such as the solar photosphere and chromosphere. The prototype instrument provides a high throughput that allows fo...
متن کاملDouble-Cavity Fabry-Perot Filters
Fabry-Perot Filters are major candidates for use as demultiplexers in wavelength division multiple access networks. In this paper we investigate the crosstalk limitations of such filters, compare their performances, and optimize the filter design to minimize the crosstalk degradation. 1 Bol.h witli the al)()rt;l.orlo for informltaiou a.icl I)ecision Ssleties. ilT.

متن کاملMicromachined Fabry-Perot Optical Filters
The design, fabrication and measured characteristics of micromachined FabryPerot (F-P) optical filters for the visible spectral range are presented. Silver films of 40-50 nm thickness, evaporated on a 300 nm thick low-stress silicon nitride membrane, are used as high-quality mirrors. Two parallel mirrors, with a square aperture of up to 2x2 mm and initial cavity gap of 1.2 μm, form a tunable Fa...
