Novel Fabry-Pérot Filter Structures for High-Performance Multispectral Imaging with a Broadband from the Visible to the Near-Infrared [PDF]

open access: yesSensors
The integration of a pixelated Fabry–Pérot filter array onto the image sensor enables on-chip snapshot multispectral imaging, significantly reducing the size and weight of conventional spectral imaging equipment. However, a traditional Fabry–Pérot cavity,

Fabry–Perot Effect Suppression in Gas Cells Used in THz Absorption Spectrometers. Experimental Verification [PDF]

open access: yesSensors
A standard measuring gas cell used in absorption spectrometers is a cylinder enclosed by two transparent windows. The Fabry–Perot effects caused by multiple reflections of terahertz waves between these windows produce significant variations in the ...

Fabry–Perot Resonance in 2D Dielectric Grating for Figure of Merit Enhancement in Refractive Index Sensing

open access: yesSensors, 2021
We have recently reported in our previous work that one-dimensional dielectric grating can provide an open structure for Fabry–Perot mode excitation. The grating gaps allow the sample refractive index to fill up the grating spaces enabling the sample to ...

Remote Non-Invasive Fabry-Pérot Cavity Spectroscopy for Label-Free Sensing

open access: yesSensors, 2022
One way of optically monitoring molecule concentrations is to utilise the high sensitivity of the transmission and reflection rates of Fabry-Pérot cavities to changes of their optical properties.

Anticaustics in a Fabry–Perot interferometer

open access: yesJournal of the Optical Society of America A, 2022
We address the response of a Fabry–Perot interferometer to a monochromatic point source. We calculate the anticaustics (that is, the virtual wavefronts of null path difference) resulting from the successive internal reflections occurring in the system.

THZ FABRY-PEROT SPECTROMETER [PDF]

open access: yesProceedings of the 2021 International Symposium on Molecular Spectroscopy, 2021
The development of Cavity-Enhanced Techniques and Cavity Ring Down Spectroscopy has allowed many sensitive infrared measurements to be undertaken. We have constructed a THz resonator with a high finesse to form the basis of a new instrument for sensitive cavity enhanced THz measurements.

Holographic Fabry–Perot spectrometer [PDF]

open access: yesOptics Letters, 2011
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.

Resonance characteristics of transmissive optical filters based on metal/dielectric/metal structures [PDF]

open access: yesКомпьютерная оптика, 2020
The resonance characteristics of the Fabry-Pérot resonator modes supported by metal/dielectric/metal planar structures are studied in the case of absorbing media for near-to-normal light incidence.
