Infrared Remote Sensing Using Low Noise Avalanche Photodiode Detector

Autor: Mathew, Joice, Gilbert, James, Sharp, Robert, Grigoriev, Alexey, Cardena, Nicolas, Yebra, Marta

For a remote sensing optical payload to achieve a Ground Sampling Distance of ~ 10-30 m, a critical problem is platform-induced motion blur. While forward motion compensation can reduce this transit speed, it comes at the expense of a more challengin

Emu: A Case Study for TDI-like Imaging for Infrared Observation from Space

Autor: Mathew, Joice, Gilbert, James, Sharp, Robert, Grigoriev, Alexey, Rains, Adam D., Moore, Anna M., Vaccarella, Annino, Magniez, Aurelie, Chandler, David, Price, Ian, Casagrande, Luca, Žerjal, Maruša, Ireland, Michael, Bessell, Michael S., Herrald, Nicholas, King, Shanae, Nordlander, Thomas

A wide-field zenith-looking telescope operating in a mode similar to Time-Delay-Integration (TDI) or drift scan imaging can perform an infrared sky survey without active pointing control but it requires a high-speed, low-noise infrared detector. Oper

Thermal Tides in the Martian Atmosphere near Northern Summer Solstice Observed by ACS/TIRVIM onboard TGO

Autor: Fan, Siteng, Guerlet, Sandrine, Forget, François, Bierjon, Antoine, Millour, Ehouarn, Ignatiev, Nikolay, Shakun, Alexey, Grigoriev, Alexey, Trokhimovskiy, Alexander, Montmessin, Franck, Korablev, Oleg

Thermal tides in the Martian atmosphere are analyzed using temperature profiles retrieved from nadir observations obtained by the TIRVIM Fourier-spectrometer, part of the Atmospheric Chemistry Suite (ACS) onboard the ExoMars Trace Gas Orbiter (TGO).

Report

Linear-mode avalanche photodiode arrays for low-noise near-infrared imaging in space

Autor: Gilbert, James, Grigoriev, Alexey, King, Shanae, Mathew, Joice, Sharp, Rob, Vaccarella, Annino

Astronomical observations often require the detection of faint signals in the presence of noise, and the near-infrared regime is no exception. In particular, where the application has short exposure time constraints, we are frequently and unavoidably
