A Fabry-Perot (F-P) based phase demodulation of heterodyne light-induced thermoelastic spectroscopy (H-LITES) is demonstrated. The vibration of quartz tuning fork (QTF) was detected by using F-P ...

A Fabry-Perot device becomes a light generator when a laser medium is used in the cavity, otherwise it is a passive filter. See distributed feedback laser and etalon. Advertisement.

Etalons are widely used in telecommunications, lasers, and spectroscopy to control and measure the wavelengths of light. Recent advances in fabrication techniques, developed by Optical Surfaces Ltd, ...
