Paper Abstract

The imaging properties of a gamma-ray telescope which employs a coded aperture in conjunction with a modular detection plane have been investigated. Gaps in the detection plane, which arise as a consequence of the design of the position sensitive detector used, produce artifacts in the deconvolved images. The effect is generally to reduce the signal to noise ratio for the detection of point sources. The application of an iterative image processing algorithm is shown to restore the image quality to that expected from an ideal detector.
