Abstract
A number of etalons together are used to extract the velocity, density and temperature of a scattering medium, such as the atmosphere. An optical air data sensor system incorporates the structure and operation for outputting laser light at a volume of air so as to be scattered by molecules and aerosols in the air volume being scanned; receiving the scattered laser light via a collecting optics assembly; splitting the received scattered laser light from the input optical fiber into a plurality of scattered light emissions; collimating each of the plurality of scattered light emissions; inputting the plurality of collimated light emissions into corresponding ones of a plurality of Fabry-Perot etalons; and imaging each of the plurality of collimated light emissions from the plurality of Fabry-Perot onto corresponding ones of a plurality of non-imaging detectors.
