Abstract
A system for obtaining air data for a vehicle comprises a laser device that emits laser light pulses, and transmit optics that transmits the light pulses into an external air volume adjacent to the vehicle. The system also includes receive optics that collects scattered portions of the light pulses from the external air volume, and a whispering gallery mode (WGM) frequency discriminator that receives the scattered portions of the light pulses from the receive optics. The WGM frequency discriminator includes at least one WGM resonator that outputs a selected portion of the light pulses at one or more optical signal frequencies via tuning the WGM resonator other than by an electro-optic effect. An optical detector samples the selected portion of the light pulses from the WGM frequency discriminator, and converts the sampled light pulses to scalar values. A processing unit receives and records the scalar values from the optical detector.
