FAST RESPONSE MULTI-COLOR PYROMETER

THE MEASUREMENT OF THE SURFACE TEMPERATURE OF MATERIALS AND SYSTEMS DURING SIMULATED REENTRY CONDITION TESTING IN HYPERVELOCITY RANGE AND TRACK TEST FACILITIES IS NECESSARY FOR THE DEVELOPMENT OF THESE MATERIALS AND SYSTEMS. TEMPERATURE MEASURING INSTRU MENTATION IS NOT CURRENTLY AVAILABLE TO ADEQUATELY MEET THIS NEED. IT IS PROPOSED THAT A FAST-RESPONSE, MULTI-COLOR PYROMETER BE DEVELOPED WHICH WOULD MEASURE TEMPERATURES ABOVE 1200 AND HAVE A RESPONSE TIME OF 50 NANOSECONDS OR LESS. THE OBJECTIVE OF PHASE I OF THIS EFFORT WILL BE TO VERIFY THE FEASIBILITY OF DEVELOPING THIS INSTRUMENT AND IN DETERMINING ITS PERFORMANCE LIMITATIONS. DATA WHICH WILL PERMIT AN OPTIMIZED SELECTION OF COMPONENTS AND SYSTEM DESIGN WILL BE OBTAINED.
