Paper Abstract

The Photon Counting Camera (PCC) is a single-photon sensitive laser communication camera that will launch on board the NASA PSYCHE spacecraft, part of the Deep-Space Optical Communication (DSOC) technology demonstration mission. The PCC comprises a single-photon sensitive Geiger-mode Avalanche Photo Diode (GmAPD) array connected to an electronics board designed to power, configure, and read out the array. The logic on the electronics board prevents accidental damage to the array, provides health and status information about the array and provides a simple interface to the downstream data processing modules. The array and electronics board are mounted into the chassis, which provides precise alignment between the optics bench and the detector as well as a path to radiate waste heat. We discuss the current design of the camera, including the electronic, thermal, and structural design. We also discuss some of the design challenges and our roadmap to building the flight unit.
