Abstract
SIGNIFICANT GAPS EXIST IN THE ABILITY OF CURRENT OPTICAL P PARTICLE COUNTERS TO PROVIDE THE INFORMATION NECESSARY TO PROPERLY CHARACTERIZE THE NATURE OF THE ATMOSPHERIC PARTICLE CONCENTRATIONS. IN PARTICULAR, SINCE SPHERICAL TESTPARTICLES OF KNOWN SIZE DISTRIBUTIONS ARE USED FOR CA CALIBRATION, THERE IS PRESENTLY NO KNOWN RELIABLE WAY TO OPTICALLY MEASURE THE IRREGULARLY SHAPED PARTICLES WHICH C COMMONLY OCCUR IN NATURE. PREVIOUS EFFORTS HAVE NOT BEEN ABLE TO SIMULTANEOUSLY OBSERVE PARTICLES AS THEY APPEARED INTHE COUNTER'S SAMPLE VOLUME, SO THERE WAS NO WAY TO DETERMINE THE COUNTER'S SAMPLE VOLUME, SO THERE WAS NO WAY TO DETERMINE THE COUNTER'S RESPONSE TO DIFFERENT PORTIONS OF THE DEPTH OF FIELD. THIS PROJECT WILL UTILIZE HOLOGRAPHIC TECHNIQUES WHICH WILL ALLOW NEW THREE DD DIMENSIONAL VISUALIZATIONS OF PARTICLES AS THEY PASS THROUGHA COUNTER'S TEST VOLUME. THE CHIEF OBJECTIVE OF THIS P PROJECT IS TO SIMULTANEOUSLY EXAMINE PARTICLES WITH A HOLOGRAPHIC SYSTEM AND A SELECTED PARTICLE MEASURING SYSTEMS CORPORATION PARTICLE COUNTER. AN ASSESSMENT WILL BE MADE OF THE POTENTIAL OF HOLOGRAPHY TO FUNCTION AS I IMPROVED CALIBRATION TECHNIQUES FOR OPTICAL COUNTERS. THESEOBJECTIVES WILL BE ACCOMPLISHED BY SLAVING A HOLOGRAPHIC SY SYSTEM TO A SELECTED COMMERCIAL PROBE AND OPERATING BOTH INSTRUMENTS IN A MEDIUM SPEED WIND TUNNEL. THE POTENTIAL COMMERCIAL APPLICATION AS DESCRIBED BY THE AWARDEE: THE PRIMARY COMMERCIAL APPLICATION OF THIS WORK WILL BE IN POLLUTION MEASUREMENTS. AEROSOLS MAKE UP AN EXTREMELY I IMPORTANT PART OF ATMOSPHERIC POLLUTANTS, AND ACCURATE MEASUREMENT IS ESSENTIAL FOR COMMERCIAL OPERATIONS SEEKING TO COMPLY WITH ENVIRONMENTAL LAWS AND REGULATIONS. IT IS ,THEREFORE, ANTICIPATED THAT THERE WILL BE EXTENSIVE APPLI- CATION FOR THIS WORK IN HEAVY INDUSTRIES. AS SUCH MEAS MEASUREMENTS ARE ALSO REQUIRED BY THOSE ATTEMPTING TO E ENFORCE SUCH LAWS, USE WILL ALSO BE MADE OF THIS WORK BY THE FEDERAL GOVERNMENT. IN ADDITION, THERE ARE PURELY SCIENTIFIC APPLICATIONS BY WEATHER RESEARCHERS SEEKING TO UNDERSTAND SUCH PHENOMENA AS RAINDROP NUCLEATION.
