Recent developments in detection of neutral atoms will enable construction of space-based imagers that may reveal the global structure and dynamics of the terrestrial magnetosphere. The principal technical challenge of imaging low energy neutral atoms (LENAs) having energies < 30 keV is separating them from the intense UV background, to which LENA detectors are sensitive, with minimal loss of trajectory and energy information. Three instrument concepts for separating LENAs from the background UV are presented: LENA charge conversion via transmission through an ultrathin carbon foil and subsequent electrostatic deflection, UV grating polarizers and attenuators, and high frequency shutters. Hardware associated with each of these concepts is mated to a detector section that provides imaging, coincidence, and, if required, time-of-flight measurements.
