Measurement and Visualization of Large Aero-Optics Wavefront Distortion Field in Wind Tunnel Testing

Abstract:

A method of measuring wavefront distortion field is presented in this paper, which gets the OPD through measuring deviation displacement field induced by the beams from center of camera to the mark points crossing the flow field. The experiments of a trans-aerosphere vehicle model in 2 meter supersonic tunnel have demonstrated that the method of this paper can be used to measure the large field of wavefront distortion, and the structures of wavefront distortion generated by oblique shock waves of the vehicles head and wing are correct. This method is simple and provides a new way to measure and observe aero-optics phenomena.
