Speckle imaging with the PAPA detector

Abstract

A new 2-D photon-counting camera, the PAPA (precision analog photon address) detector has been built, tested, and used successfully for the acquisition of speckle imaging data. The camera has 512 × 512 pixels and operates at count rates of at least 200,000/sec. In this paper we present technical details on the camera and include some of the laboratory and astronomical results which demonstrate the detector's capabilities.
