Paper Abstract

The camera chosen for this study uses a narrow-band uv bandpass filter with a center wavelength at 254_nm and a refractive-optic uv lens. The uv image detector is a an ITT Type #F4146 photon-counting imaging detector with a uv sensitive photocathode used in conjunction with a Surface Science Laboratories position computer to generate the output images. This combination of filter and photocathode make the camera essentially solar-blind. On a clear day and in full sunlight there are essentially no background photon counts from outside scenes. Examples of a few open-flame and other uv sources and images produced by this camera are presented.
