Abstract
An integrated optical system illuminates an ultraviolet spatial detector with an image from a field of interest. The ultraviolet spatial detector is comprised of an electron multiplying microchannel plate and a 100 pixel discrete anode array using a high strip current microchannel plate. The discrete anode array preserves the spatial distribution of the image. The ultraviolet spatial sensor has a wide field of view. The ultraviolet spatial detector has a photon counting sensor capable of detecting ultraviolet sources to determine their position to within plus or minus 4.5 degrees.
