ABSTRACT:
A system using Lidar/Laser anemometry for measuring the position of the normal shock wave and air velocity in the inlet of a supersonic engine is described, A laser beam is focused over a region in the inlet where the shock is expected to be. Small particles in the inlet air each reflect the light which is Doppler shifted according to the air velocity in that point. The system and method utilizes the relative amplitude of two peaks in the Fourier transform of the optical return signal to determine if the position of the shock is within the focal region of the laser.
