Novel Fabry-Perot interferometer measurements of F-region ion temperature
[1] Novel optical measurements of F-region ion temperatures have been made in conjunction with thermospheric neutral temperatures. A ground-based FabryPerot interferometer has been used to observe high-latitude Fregion ion temperatures using the O(P) auroral emission at 732 nm, and upper-thermospheric neutral temperatures using the O(D) airglow emission at 630 nm. Dual wavelength measurements w...
متن کاملHigh time resolution measurements of the thermosphere from Fabry-Perot Interferometer measurements of atomic oxygen
Recent advances in the performance of CCD detectors have enabled a high time resolution study of the high latitude upper thermosphere with Fabry-Perot Interferometers (FPIs) to be performed. 10-s integration times were used during a campaign in April 2004 on an FPI located in northern Sweden in the auroral oval. The FPI is used to study the thermosphere by measuring the oxygen red line emission...
متن کاملHigh-pressure and high-temperature characteristics of a Fabry-Perot interferometer based on photonic crystal fiber.
A fiber-optic Fabry-Perot interferometer was constructed by splicing a short length of photonic crystal fiber to a standard single-mode fiber. The photonic crystal fiber functions as a Fabry-Perot cavity and serves as a direct sensing probe without any additional components. Its pressure and temperature responses in the range of 0-40 MPa and 25°C-700°C were experimentally studied. The proposed ...
متن کاملTemperature analysis of low-expansion Fabry-Perot cavities.
Temperature dependent structural distortion at the contacted mirrors of low-expansion glass cavities can introduce changes to the cavity length independent of the length of the spacer. There are resulting temperature sensitivities of the path (m/K) at each end of a cavity that are proportional to the difference of the coefficient of thermal expansion (alpha) at the contact. The temperature sens...
متن کاملHolographic 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...
