Precision Projector Laboratory: detector characterization with an astronomical emulation testbed [PDF]

open access: yesJournal 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 ...

Fibre Bragg gratings for high spectral and temporal resolution astronomical observations [PDF]

open access: yes, 2012
Dynamic spectral analysis of astronomical events has the potential to deliver the information needed to clarify or complete important theoretical descriptions of astronomical phenomena. There is currently a lack of detailed sub-minute observations due to

The Growth of Interest in Astronomical X-Ray Polarimetry

open access: yesGalaxies, 2018
Astronomical X-ray polarimetry was first explored in the end of the 1960s by pioneering rocket instruments. The craze arising from the first discoveries of stellar and supernova remnant X-ray polarization led to the addition of X-ray polarimeters to ...

A dew detector for use with astronomical telescopes [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 1987
The design of a dew detector for use on astronomical telescopes is described. The sensing element for the detector is a piece of printed-circuit board etched with a grid pattern of metallic and nonmetallic areas. The sensor grid pattern is produced on the circuit board by photoetching from a positive contact-printing mask.

Josephson junction detector for astronomical applications [PDF]

open access: yesRevue 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.
