Precision Projector Laboratory: detector characterization with an astronomical emulation testbed [PDF]
Journal of Astronomical Telescopes, Instruments, and Systems, 2019 As astronomical observations from space benefit from improved sensitivity, the effectiveness of scientific programs is becoming limited by systematics that often originate in poorly understood image sensor behavior. Traditional, bottom-up detector characterization methods provide one way to model underlying detector physics, and generate ever more ...

ATLAST detector needs for direct spectroscopic biosignature characterization in the visible and near-IR [PDF]
, 2015 Are we alone? Answering this ageless question will be a major focus for astrophysics in coming decades. Our tools will include unprecedentedly large UV-Optical-IR space telescopes working with advanced coronagraphs and starshades.

GravityCam: higher resolution visible wide-field imaging [PDF]
, 2018 The limits to the angular resolution has, during the latest 70 years, been obtainable from the ground only through extremely expensive adaptive optics facilities at large telescopes, and covering extremely small spatial areas per exposure.

Josephson junction detector for astronomical applications [PDF]
Revue de Physique Appliquée, 1974 A wide-band detector for the 1.0 to 1.6 mm atmospheric transmission window has been developed for astronomical observations at the McDonald Observatory 2.7 m optical telescope. For observations of continuum astronomical sources, the relevant figure of merit is the « Noise Equivalent Temperature » or δ Trms.

Automated reduction of submillimetre single-dish heterodyne data from the James Clerk Maxwell Telescope using ORAC-DR [PDF]
, 2015 With the advent of modern multi-detector heterodyne instruments that can result in observations generating thousands of spectra per minute it is no longer feasible to reduce these data as individual spectra.

The Infrared Imaging Spectrograph (IRIS) for TMT: Data Reduction System [PDF]
, 2016 IRIS (InfraRed Imaging Spectrograph) is the diffraction-limited first light instrument for the Thirty Meter Telescope (TMT) that consists of a near-infrared (0.84 to 2.4 $\mu$m) imager and integral field spectrograph (IFS). The IFS makes use of a lenslet
