We investigate the characteristics of imaging systems in the 20 keV-10 MeV energy band which incorporate the high spatial and spectral resolution of planar germanium strip detectors. A Compton scatter telescope provides sensitivity above approximately 250 keV a coded aperture positioned above the top germanium detector plane of the Compton telescope forms a coded-aperture telescope with sensitivity in the 20-250 keV band. The high spectral resolution and spatial resolution of germanium strip detectors provides a Compton telescope with dramatically improved energy resolution, angular resolution, and sensitivity compared with previous Compton instruments. Such a system has excellent angular response for point source identification and spectroscopy and also provides response to high energy diffuse emissions such as the Galactic 511 keV line emission and Al26 emission. Monte Carlo simulations of the concept and estimates of the sensitivity shall be presented.
