New high spatial and energy resolution silicon and CdZnTe pixel detectors have been developed for wide applications in high energy x-ray and low energy gamma-ray astronomy. The proposed use of these novel devices are in a wide field of view, imaging, x-ray and low energy gamma ray all sky monitor (AXGAM) instrument. It can also be used with focussing type x-ray imaging telescopes as it has high (300 x 300 micron) spatial resolution. The high stopping power of the CdZnTe detectors combined with low-noise front-end readout electronics makes it possible to bring an order of magnitude improvement in spatial (angular) and energy resolution for high energy x-ray and low energy gamma-ray detection and imaging. The AXGAM instrument will be built in the form of a fine coded mask placed over two-dimensional, high spatial resolution and low energy threshold silicon and CdZnTe pixel detector arrays. The preliminary test results obtained from the initial prototype silicon and CdZnTe pixel detectors with low-noise data acquisition system will be presented. Its application for the AXGAM instrument and other space missions such as the CONSTELLATION Mission will be discussed.
