Fabry-Perot filters used for optical preprocessing.
A Fabry-Perot etalon placed in the object plane of a coherent optical processing system can be used as a variable bandpass preprocessing filter. Use of this filter leads to improved correlation signals in a matched spatial filter system. Experimental results are shown and compared with results obtained by two other preprocessing methods.
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...
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 کاملNovel tunable liquid crystal Fabry-Perot filters for Fiber-Optical system
Tunable filters with a wide tunable range that cover the whole C-band , or L-band, or both, have been found wide applications in fiber optical communication system, mainly in three domain: tunable laser, wavelength division multiplexing systems (WDM), and channel monitoring. Due to the growing demand in bit-rate and number of channels in WDM system, tunable narrow band pass filters are required...
متن کاملOptical Torques in Suspended Fabry-Perot Interferometers
High-power Fabry-Perot cavities with suspended mirrors are employed in gravitational wave detection. The mirrors in such interferometers are subject to forces and torques that are exerted by light pressure. This article derives a closed-form expression for the static torsional stiffness due to this effect. The torsional stiffness is shown to scale as the fourth power of the beam spot size. In p...
