Abstract
CHARACTERIZING THE OPTICAL PROPERTIES OF INDIVIDUAL AEROSOL PARTICLES IN THE AEROSPACE ENVIRONMENT REQUIRED TO ALLOW PERFORMANCE ANALYSIS OF OPTICAL AND INFRARED SYSTEMS AND OPTICAL OBSCURATION COUNTERMEASURES. THERE EXISTS A NEED TO DEVELOP NEW INSTRUMENTATION WHICH CAN AUTOMATICALLY AND REMOTELY (IN-SITU) MEASURE AND RECORD THE TOTAL SCATTERING PATTERN FROM INDIVIDUAL AIRBORNE PARTICLES OF DIFFERENT MATERIAL AND SHAPES UNDER VARIOUS NATURAL AND MAN-MADE ATMOSPHERIC CONDITIONS. KNOWLEDGE OF PHYSICAL/OPTICAL PROPERTIES OF ATMOSPHERIC ATMOSPHERIC AEROSOLS WILL GREATLY ENHANCE THE CAPABILITY OF MODELING ATMOSPHERIC TRANSMISSION AND PREDICTING PERFORMANCE OF OPTICAL AND INFRAFED SYSTEMS. THE OBJECTIVE OF THE PHASE I EFFORTS ARE TO IDENTIFY THE SYSTEM REQUIREMENTS, INVESTIGATE THE TECHNICAL FEASI BILITY OF THE DEVELOPED CONCEPT AND DESIGN A PROTOTYPE SYSTEM INCLUDING A PARTICLE (INLET) SAMPLING SYSTEM FOR POTENTIAL AIRCRAFT USAGE, IDENTIFY LIGHT SOURCE, OPTICS AND DETECTORS FOR THE SYSTEM, AND A DATA ACQUISITION SYSTEM. THE PROPOSED APPROCH IS TO MEASURE THE SPECTRAL AND ANGULAR VARIATION OF SCATTERED LIGHT PATTERNS OF INDIVIDUAL PARTICLES OVER 4 STERADIANS BY EMPLOYING MULTIPLE SOURCES AND DETECTORS AND A FAST RESPONSE DATA ACQUISITION SYSTEM. PHASE I RESULTS ARE INTENDED TO PROVIDE DETAILS OF SYSTEM DESIGN, HARDWARE IDENTIFICATION AND THEORETICAL ANALYSIS THAT WILL DIRECT THE IMPLEMENTATION OF PHASE II - THE ACTUAL CONSTRUCTION OF THE SYSTEM.
