Abstract
We present the instrument design, the image motion correction algorithm, and the predicted performance of the Ultraviolet Imager (UVI) proposed for the Jupiter Magnetospheric Explorer (JMEX) mission. The JMEX mission is a small explorer mission (SMEX) designed to observe the Jovian system and to study the dynamical relationship between Jupiter's magnetosphere and Io, the primary source for the Io plasma torus. JMEX was selected as one of six SMEX missions for review by NASA following additional design and analysis. While not selected for flight, the design includes several innovative design features which permit 0.25" imaging on a SMEX class spacecraft which are of general interest. The UVI consists of the Ultraviolet Telescope (UVT) and the Ultraviolet Imager Instrument Package (UVIIP). The UVT is a 50 cm Cassegrain telescope, and the UVIIP consists of an elliptical tertiary mirror, an eight position filter/prism wheel, a cross-delay line microchannel plate detector and a visible light image motion sensor. The integrated system will provide 0.25" imaging over a 100" field of view between 115 and 200nm.
