Lederman M. H. Bloom Polytechnic Institute of Brooklyn, Preston R. Bassett Research Laboratory, Farmingdale, N. Y. The application of Raman scattering to air pollution detection monitoring and measurement is considered. Some theoretical as well as practical aspects of the problem are discussed. Positive as well as negative features of the Raman scattering diagnostic techniques are pointed out. The problems associated with the utilization of lasers, the power requirements, frequency selection, pulse repetition rate, and reliability are discussed. It is concluded that the diagnostic technique utilizing Raman scattering has sufficient outstanding features to make it particularly suitable for the task at hand.
