Atmospheric Transmission Measurements Using Infrared Lasers And Fourier Spectroscopy - Techniques, Results, And Comparisons To Computer Models

The design and effective utilization of many infrared systems now being deployed require a detailed knowledge of the transmission properties of the earth's atmosphere. A measurement system recently used for transmission studies at several infrared laser wavelengths is described. Results of comparisons of experimental data to computer generated atmospheric transmission predictions are presented and discussed. The application of Fourier Transform Spectroscopy (FTS) to atmospheric transmission studies is described and a measurement technique using laser measurements to calibrate high resolution FTS data is presented.
