Paper Abstract

The objective of this effort was to compare the resolution and contrast characteristics of ultraviolet imagers with and without an intensifier. This was accomplished by first observing several bar patterns in the laboratory. Then both imagers were taken outside of the laboratory during daylight conditions and observations were made of objects with limited contrast. It was found that in all the measurements the nonintensified imager performed considerably better than the intensified imager. In fact in an observation of low contrast, with the nonintensified imager it was possible to distinguish small intensity variations, whereas with the intensified imager these variations were within the noise level of the instrument. The noise level of the intensified imager was also measured with high gain and with low gain and a definite variation was found.
