Precision Projector Laboratory: detector characterization with an astronomical emulation testbed
The "crosshatch" pattern is a recurring "feature" of HgCdTe arrays, specifically the Teledyne HAWAII family of near infrared detectors. It is a fixed pattern of high frequency QE variations along 3 directions generally thought to be related to the crystal structure of HgCdTe. The pattern is evident in detectors used …
