Abstract:
THE OXYGEN MOLECULE HAS A NUMBER OF WEAK ABSORPTION LINES INTHE 7000 A SPECTRAL REGION. BY COOLING, THE R1 LINE OF RUBY(A12O3 : CR+3) CAN BE SHIFTED TO COINCIDE WITH 50% ABSORPTION AT LINE CENTER IN THE SOLAR SPECTRUM. RUBY FLUORESCES WITH HIGH QUANTUM EFFICIENCY, WITH A TIME CONSTANT OF APPROXIMATELY 4 MS AT THE TEMPERATURES OF INTEREST. BY DETECTING THE RERADIATED LIGHT, THE RUBY CRYSTAL IS USED AS A TUNABLE NARROW BAND FILTER; THE BANDWIDTH CAN BE LESS THAN 0.4 A (FWHM). THE COLUMN DENSITY OF OXYGEN ALONG A GIVEN LINE OF LIGHT. TWO IMPORTANT USES OF SUCH A SENSOR ARE REMOTE SENSING FROM A SPACE PLATFORM OF CLOUD TOP HEIGHT, AND GROUND BASED ESTIMATION OF TIME DISPERSION OF A PULSE PROPOGATING THROUGH CLOUDS FROM SPACE. THE PROPOSED SPECTRAL LINE DISCRIMINATOR COULD BE VERY LIGHT WEIGHT ( 100 GM) AND HAVE LOW POWER CONSUMPTION (A FEW MW). THE RESEARCHERS PROPOSE TO TEST THIS CONCEPT IN A SIMPLE EXPERIMENTAL CONFIGURATION THAT WILL DEMONSTRATE OPERATION OF THE RUBY CRYSTAL IN THE INTENDED MODE, AND TO NUMERICALLY SIMULATE SEVERAL OF THE POSSIBLE FINAL FORMS OF THE INSTRUMENT.Small Business Information at Submission:Principal Investigator:
