This study presents an original optical system designed for measuring the free surface velocity for shock wave diagnostics. The system is based on a solid Fabry–Perot etalon interferometer coupled to a tunable, single frequency laser. The setup assembled for this purpose can measure velocities up to 200 m s−1 and has a resolution time of about 1 ns ...

Analytical method to find the optimal parameters for gas detectors based on correlation spectroscopy using a Fabry-Perot interferometer [PDF]
Several designs of infrared sensors use a Fabry-Perot Interferometer (FPI) to modulate the incident light. In this work we analyse the particular case where the FPI fringes are matched with very well defined ro-vibrational absorption lines of a target ...

Characterization of a novel three-section tunable slotted fabry-perot laser [PDF]
A novel three-section tunable slotted-Fabry-Perot laser has been examined. Characterizations of the linewidth, SMSR and RIN indicate that this type of laser may be a suitable source for dynamic networks employing advanced optical modulation ...

Self-coherent optical transmission using a narrow linewidth tunable slotted fabry-perot laser [PDF]
A narrow linewidth slotted Fabry-Perot laser has been employed in a self-coherent optical transmission system. A comparison of the system performance of the tunable slotted laser with a SG-DBR laser has also been ...

Micro-machining Techniques for the Fabrication of Fibre Fabry-Perot Sensors [PDF]
Fabry-Perot optical fibre sensors have been used extensively for measuring a variety of parameters such as strain, temperature, pressure and vibration. Conventional extrinsic fibre Fabry-Perot sensors are associated with problems such as calibration of ...

Pulsed laser linewidth measurement using Fabry–Pérot scanning interferometer
We apply the Fabry–Pérot (FP) scanning interferometer, which is normally used for continuous wave (CW) laser linewidth measurement, for the measurement of pulsed laser linewidths.
