Abstract : Optically smart surfaces are being developed as wind tunnel diagnostic techniques for the Wright Laboratory. The optically smart surfaces are holographic optical elements constructed by flow coating an aluminum plate with photoresist as the emulsion material. Survivability of these optically smart surfaces was tested in the Mach 3 High Reynolds Number Facility. The surfaces did not survive at angle of attack to the freestream flow for higher Reynolds numbers and did survive when the surface was parallel to the freestream flow....
