Poisson wavefront imaging in photon-starved scenarios
Seungman Choi, Peter Menart, Andrew Schramka +4
Low-photon phase imaging is essential in applications where the signal is limited by short exposure times, faint targets, or the need to protect delicate samples. We address this c…
Optical Response in Spintronic Poisson Bolometers
Ziyi Yang, Sakshi Gupta, Jehan Shalabi +5
Analog bolometers based on temperature-dependent phase-transition materials such as vanadium oxide (VOx) and barium titanate (BTO) represent the state of the art in uncooled infrar…
Design of Microlens Arrays for Thermal Imaging with Spintronic Poisson Bolometers
Ziyi Yang, Leif Bauer, Zubin Jacob
Infrared (IR) detectors are widely used due to their ability to sense thermal radiation. Recently, a room-temperature infrared detector known as the spintronic Poisson bolometer wa…
Enhanced Sensitivity to Blackbody Radiation in Spintronic Poisson Bolometers
Ziyi Yang, Sakshi Gupta, Jehan Shalabi +5
High-sensitivity long-wave infrared (LWIR) detection is crucial for observing weak thermal radiation. Recently, the Poisson bolometer has been proposed as a fundamentally new platf…
Photon-starved imaging through turbulence at the diffraction limit
Seungman Choi, Peter Menart, Andrew Schramka +4
Ground-based imaging systems struggle to achieve diffraction-limited resolution when atmospheric turbulence and photon scarcity act simultaneously. In this regime, conventional ada…
Long wave infrared detection using probabilistic spintronic bolometer arrays
Utkarsh Singh, Leif Bauer, Angshuman Deka +5
The use of probabilistic spintronic devices for infrared radiation detection has introduced a shift in approach to thermal imaging. The integration of probabilistic magnetic tunnel…
