We illustrate these new imaging analysis techniques using the data acquired by the wide- eld high resolution hard X-ray telescope ProtoEXIST2 during the high-altitude balloon ight in Fall, In Section 2, we review the basic parameters of the ProtoEXIST2 telescope. Planning for CTA in the U.S. began in the context of the Advanced Gamma-ray Imaging System (AGIS) concept, consisting of an array of high-angular-resolution, wide-field telescopes with novel Schwarzschild-Couder optics. This work led to positive endorsements by the HEPAP PASAG panel  and the Astro Decadal survey .

Details are presented of an atmospheric Cherenkov telescope for use in very high energy gamma-ray astronomy which consists of a cluster of close-packed photomultiplier tubes at the focus of a 10 meter optical reflector.
The images of the Cherenkov flashes generated both by gamma-ray and charged cosmic-ray events are digitized and by: The Liquid Xenon Gamma-Ray Imaging Telescope (LXeGRIT) is the first realization of a liquid xenon time projection chamber for Compton imaging of MeV γ-ray sources in astrophysics.
A liquid xenon time projection chamber (LXeTPC) has been developed to image cosmic γ-rays in the energy band –20 MeV. Its performance as Gamma Ray Imaging Telescope (LXeGRIT instrument) has been tested during a high altitude balloon flight (Spring ’99, New Mexico).Cited by: The detector, based on liquid xenon time-projection chambers, is optimized for approximately - 10 MeV and combines high efficiency within a 3 sr field-of-view with approximately 1 degree(s) angular resolution and excellent background reduction by: 2.

However, when the photons exceed energies of ~ keV (called gamma-ray photons andtimes greater than the energy of an optical photon), such direct methods of imaging become increasingly difficult.
