Detector Measurements/Models 3
- Bradley Kelman (OU)
Inter-pixel capacitance (IPC) is an important parameter which needs to be measured accurately so that the required corrections can be applied to the measured conversion gain and hence all the derived detector performance characteristics. Different methods such as auto-correlation, absolute capacitance, hot-pixel, cosmic ray hits or single-pixel reset methods can be used to measure the...
The Nancy Grace Roman Telescope is an upcoming NASA observatory that will investigate the origins of cosmic acceleration using weak gravitational lensing (WL). WL induces percent-level distortions in galaxy shapes, and accurate WL measurements are highly sensitive to the point-spread function (PSF). Thus, it is essential to characterize detector effects, particularly nonlinear behaviors that...
We implemented an electron avalanche photodiode (e-APD) in the MIRC-X instrument, which is an upgrade of the six-telescope near-infrared imager MIRC, at the CHARA array. This technology improves the sensitivity of near-infrared interferometry.
We aim to characterize a near-infrared C-RED ONE camera from First Light Imaging (FLI) using an e-APD from Leonardo (previously SELEX).
We first...
