Aero-Optics Measurement System for the AEDC Aero-Optics Test Facility
Abstract
A fundamental problem associated with hypersonic, endoatmospheric, optically guided vehicles for interception of ballistic reentry vehicles is target image degradation caused by the complex flow field of the intercept vehicle. The image degradation mechanisms are collectively referred to as aero- optics (AO) effects. The AEDC aero-optics measurement system provides the hardware, software, techniques, and expertise for measurement of the fundamental AO effects parameters in a ground test facility. The AO measurement system is presently configured for use in AEDC Tunnel C, a continuous flow hypersonic wind tunnel. AO effects measurements are based upon image analysis, image jitter, and holographic interferometry techniques. The primary purpose of this report is to provide hardware descriptions for the imaging and holography systems and their associated data acquisition and data reduction systems. Information is also provided in the appendixes, which describe several AO measurements technology advances in various stages of development.
