Abstract:

The report summarized technical details of the work performed from June 23 to September 23, 1971. A detailed discussion of work performed at the Ohio State Univ. Electro-Science Laboratory is presented. This work consisted of atmospheric transmittance calculations near 5 micrometer and the design of a laboratory experiment to determine the transmittance of CO laser radiation through synthetic atmospheres. Computer programs have been written to calculate the molecular absorption due to atmospheric absorbers near 5micrometer. The type of calculations include computer plots of the calculated spectra, more accurate transmittance values at the frequencies of the CO laser emissions for horizontal paths, and transmittance values at the frequencies of the CO laser emissions for slant paths through the atmosphere. Preliminary calculations are presented with water vapor as the only atmospheric absorber considered. The design of an experiment to measure the transmittance of the CO laser emissions through simulated atmospheres is described. Specific topics covered are the CO laser, selection of the emission lines to be measured, the multiple traversal cell, and the experimental procedure.
