摘要

Abstract: The Multi-Anode Microchannel Array (MAMA) detector system is a true photon-counting imager which records the position and arrival time of each detected photon for post facto image reconstruction analysis. Imaging by time-tag photon detection with the MAMA is being used for image stabilization on sounding rockets, and for speckle interferometry and speckle image reconstruction at ground-based telescopes using the Stanford University Speckle Interferometer System (SUSIS). This paper describes the construction and mode-of-operation of the MAMA time-tag photon-detection system, including recent improvements to the data-handling system which permit a data-recording rate in excess of 1 M event s$+$MIN@1$/. The intrinsic time resolution of the MAMA detector system is $LS 300 ns and the time resolution of the SUSIS used to date is 3.2 $mu@s for each detected photon. A number of examples of both laboratory data and visible-light speckle interferometric deconvolutions and two- dimensional speckle image reconstructions are presented.!10
