Abstract

See full text

The invention is directed to a device and method for conducting measurement of a Doppler shift caused by molecular and aerosol movement while simultaneously providing measurement of temperature using LIDAR. The device incorporates a light source; and a Fabry-Perot etalon having a resonant cavity formed with two plane parallel reflecting surfaces, wherein the light source is positioned relative to the a Fabry-Perot etalon such that light is injected into a plane parallel resonant cavity of the Fabry-Perot etalon at an angle of incidence other than normal to the reflecting surfaces. The Fabry-Perot etalon may be formed with each of the parallel reflecting surfaces having different reflectivities. The light source may be positioned to direct the light to bypass a first reflective surface of the plane parallel resonator cavity, and/or implemented using a divergent light source. In addition, the Fabry-Perot etalon may be formed to include an aperture in at least one mirror surface or an edge portion in at least one mirror surface through which the light is directed into the resonant cavity. The device may also incorporate a detector for detecting a fringe pattern outputted by the Fabry-Perot etalon.
