Associated Platforms POLAR Related Data Sets View all records related to this instrument Description 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.
