  skos:definition """The Ultraviolet Imager (UVI) is a two dimensional imager sensitive to far
ultraviolet wavelengths flown on the POLAR spacecraft. With its 8 degree
circular field of view, it will image the sunlit and nightside polar regions of
the earth. The UVI is able to detect and provide images of very dim emissions
with a wavelength resolution never achievable before. The highly sensitive
instrument will conduct observations of both the sunlit and nightside polar
regions in the far ultraviolet wavelengths. The resulting images will help
quantify the overall effects of solar energy input to the earth's polar
regions. Its scientific objectives are to image to aurora simultaneously, to
measure the total energy and characterize the energy that is deposited in the
auroral regions, to characterize the space and time variations of the aurora,
and to help correlate events in the auroral regions to other regions in the
magnetosphere.
