Abstract
The development of sophisticated Electro-Optical systems for use in a shipboard environment is somewhat hampered by the lack of reliable models of the optical turbulence effects in close proximity to the ship, caused by the ship itself. To this end, preliminary microthermal fluctuations were made on an operating aircraft carrier during July 1979, along with other optical and meteorological measurements. These microthermal fluctuation measurements are being studied to ascertain their value in the development of a suitable model. Three CONTEL model MT-2 Microthermal Probes were specially modified for shipboard measurements and remote data acquisition, and deployed at three deck level sites on the USS LEXINGTON. These sites included the forward port and starboard sponscns, and an aft starboard sponson. Data was logged once each second for nine to fourteen hour periods on three consecutive days. The measurements include periods of flight operations during which the launching of aircraft can be clearly observed as strong perturbations in the data. Analysis of the data, measurement techniques and other evidence, raises several cautions as to the application of the standard optical turbulence models. In this light, the value of the data set is discussed and the character of future measurements are suggested.
