Abstract

Multispectral transmissometer systems have been used in a large number of tests to evaluate line-of-sight transmittance through smoke screens. Analysis of the data have shown that for the same spectral band, a wide variation in measured transmittance is possible when different transmissometer systems are used. Since transmittance data is a key factor in interpreting electro-optical system performance, it is important that accurate measurements of potential countermeasures such as smoke screens be obtained. Therefore, a thorough understanding of the factors that can affect transmissometer performance is necessary. In this paper, an analysis is presented of those operational characteristics that can affect multispectral transmissometer performance. An evaluation is performed to identify the most important parameters affecting data quality and to evaluate how these factors can be expected to affect data characteristics. Results are compared with field test data and actual operating systems.
