“…Therefore, even in the absence of noise, the sensitivity of such a system is strongly affected. For these reasons the NRA's have not found use in high energy astronomy, instead applications have been attempted in nuclear medicine (Chang et al, 1975;Fleming and Goddard, 1984) and in optical and infrared astronomy (Brown, 1978;Aitken et al, 1981).…”

Coded aperture imaging in high energy astronomy represents an important technical advance in instrumentation over the full energy range from X-to y-rays and is playing a unique role in those spectral ranges where other techniques become ineffective or impracticable due to limitations connected to the physics of interactions of photons with matter. The theory underlying this method of indirect imaging is of strong relevance both in design optimization of new instruments and in the data analysis process. The coded aperture imaging method is herein reviewed with emphasis on topics of mainly practical interest along with a description of already developed and forthcoming implementations.
