Description:
A prototype airborne downlooking infrared differential absorption system using CO2 TEA (transverse excited atmospheric) lasers is described. The system uses two wavelengths and topographic reflection to measure the integrated column concentration of ozone between the laser source/receiver and a noncooperative target. A comparison is made between ozone absorption coefficients measured with TEA lasers and values reported from other sources. Ground tests utilized two 30-cm long ozone-filled test cells, one in each laser path. A correlation was observed between measurements of TEA laser pulses backscattered from a building and ultraviolet determination of ozone concentration in the cells.
