Superconducting tunnel junctions as detectors for ultraviolet, optical, and near infrared astronomy [PDF]

open access: yesAstronomy and Astrophysics, 1997
We discuss the capabilities of superconduct- ing tunnel junctions as detectors for ultraviolet, optical, and near-infrared astronomy. Such junctions have recently been shown to allow the detection of individual optical and ultraviolet photons with an inherent spectral resolu- tion related to the critical temperature of the absorbing superconductor ...

Design of microstrip-line coupled kinetic inductance detectors for near infrared astronomy

open access: yesMillimeter, Submillimeter, and Far-Infrared Detectors and Instrumentation for Astronomy XI, 2022
Kinetic inductance detectors (KID) have great potential in astronomical observation, such as searching for exoplanets, because of their low noise, fast response and photon counting characteristics. In this paper, we present the design process and simulation results of a microstrip line coupled KIDs array for near-infrared astronomical observation ...

Integration of a Testbench for the Optical and Thermal Characterization of Near-Infrared Detectors Used in Ground and Space-Based Astronomy [PDF]

open access: yesIEEE Transactions on Instrumentation and Measurement, 2021
The mercury–cadmium–tellurium (MCT) sensors are considered the ideal infrared detectors to equip the focal plane arrays (FPAs) of astronomical scientific missions. To tackle Europe to be self-sufficient on this technology and promote to reach the same maturity level attained by the current MCT sensors market leaders, the Astronomy European Infrared ...
