FEASIBILITY OF USING FLUORESCENT COLORANTS TO AFFORD CAMOUFLAGE PROTECTION AGAINST PHOTOGRAPHIC DETECTION

Abstract

Camouflage against visual observation or detection by infrared image- converters requires that the reflectance of objects be relatively low. On the other hand, camouflage against infrared-sensitive photography requires that reflectance in the appropriate spectral region be relatively high. Reasons for these restrictions are discussed. Of possible approaches to attain desired reflectance characteristics, that involving fluorescence in the near infrared is discussed. A methodology for searching for suitable dyes and the design of an instrument that can identify the invisible infrared fluorescence are described. The infrared fluorescence characteristics of over 100 dyes applied to various fabrics is given.
