Optically Smart Surfaces for Aerodynamic Measurements.
Abstract
This effort was to develop optically smart surfaces for aerodynamic measurement applications. Phase I established the feasibility of incorporating an optical sensor in a thin holographic coating placed on an arbitrary metallic surface. These holograms store a complex optical instrument which is actuated by impinging an 'address' beam. Information is impressed by the sensor upon the address beam before it is returned to a receiver. Phase II moved these sensors from the basic research laboratory to a wind tunnel environment. Holographic sensors to measure velocity and skin friction were designed, constructed and tested in a calibration channel located at the University of California Irvine and a transonic wind tunnel located at Wright Laboratory. Efforts were made to improve sensor ruggedness and reproducibility by development techniques to produce nickel shims and mylar peel and stick sensors.
