Ozone Cues Mitigate Reflected Downwelling Radiance in LWIR Absorption-Based Ranging
Unay Dorken Gallastegi, Wentao Shangguan, Vaibhav Choudhary +4
Passive long-wave infrared (LWIR) absorption-based ranging relies on atmospheric absorption to estimate distances to objects from their emitted thermal radiation. First demonstrate…
Beam Cross Sections Create Mixtures: Improving Feature Localization in Secondary Electron Imaging
Vaibhav Choudhary, Akshay Agarwal, Vivek K Goyal
Secondary electron (SE) imaging techniques, such as scanning electron microscopy and helium ion microscopy (HIM), use electrons emitted by a sample in response to a focused beam of…
Image Reconstruction from Readout-Multiplexed Single-Photon Detector Arrays
Shashwath Bharadwaj, Ruangrawee Kitichotkul, Akshay Agarwal +1
Readout multiplexing is a promising solution to overcome hardware limitations and data bottlenecks in imaging with single-photon detectors. Conventional multiplexed readout process…
Shot noise-mitigated secondary electron imaging with ion count-aided microscopy
Akshay Agarwal, Leila Kasaei, Xinglin He +6
Modern science is dependent on imaging on the nanoscale, often achieved through processes that detect secondary electrons created by a highly focused incident charged particle beam…
