Abstract:
1. A lock-in imaging system configured for detecting disturbances in fluids including air, the system comprising: an interferometer located on an aircraft configured for producing an interference pattern by splitting a coherent beam of light into two coherent beams along two paths and recombining the two coherent beams at a junction point in front of a flight path; a plurality of mirrors configured for directing the two coherent beams toward one another at the junction point; and a telescopic imaging camera located on the aircraft configured for capturing an image of the interference pattern of the two coherent beams at the junction point where the two coherent beams of light recombine in front of the flight path; wherein at least one of the plurality of mirrors is disposed on a tip of a pair of wing, from a pair of wines of the aircraft, wherein the telescopic imaging camera is configured for detecting the disturbance of the fluid along an optical path of the two coherent beams based on an index of refraction of the image detected at the junction point in front of the flight path, and wherein the telescopic imaging camera is configured for detecting the disturbance of the fluid along the optical path of the two coherent beams based on a pressure dependent change of the index of refraction of the air.
