Abstract:
An airborne multiple field-of-view water droplet sensor includes an illumination portion and a detection portion. The illumination portion includes a first optical beam emitter configured to output a light beam. The detection portion includes a kaleidoscope configured to channel a first portion of the backscattered light towards an inner reflective surface of a circle-to-line converter, a multiple field of view subsystem having at least a first detector configured to receive light reflected by the circle-to-line converter, and a single field-of-view subsystem configured to receive a second portion of the backscattered light, the second portion not having been reflected by the circle-to-line converter. The single field-of-view subsystem may include a dual channel circular polarization detector for distinguishing between liquid water droplets and ice crystals based on information in the single field-of-view.
