NARROW-BAND ULTRAVIOLET FILTER PHOTOGRAPHY.
Abstract
The experimental program was undertaken to investigate the spectral characteristics of narrow-band ultraviolet filter photography during daylight hours for the wavelength range of 3000 to 4000 angstroms. The filters used in the study were multilayer dielectric Fabry-Perot filters with a spectral band pass of approximately 100 A covering the wavelength range of 3000 to 4000 A. The unusual penetration effects, due to ultraviolet scattering and unique contrast changes, are presented in detail. Some spectral reflectance data of selected materials for the wavelength range of 3000 to 4000 A are included within the report. Combining spectral ranges on a single piece of film for the purpose of enhancing the over-all contrast were investigated. A description of the equipment and films used in the investigation is discussed. The study shows the narrow-band ultraviolet filter photography provides very useful information for reconnaissance and surveillance applications. (Author)
