Performance of active edge pixel sensors [PDF]

open access: yesJournal of Instrumentation, 2017
To cope with the High Luminosity LHC harsh conditions, the ATLAS inner tracker has to be upgraded to meet requirements in terms of radiation hardness, pile up and geometrical acceptance. The active edge technology allows to reduce the insensitive area at the border of the sensor thanks to an ion etched trench which avoids the crystal damage produced by

3D track reconstruction capability of a silicon hybrid active pixel detector

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
Timepix3 detectors are the latest generation of hybrid active pixel detectors of the Medipix/Timepix family. Such detectors consist of an active sensor layer which is connected to the readout ASIC (application specific integrated circuit), segmenting the

Sun Sensor Based on a Luminance Spiking Pixel Array [PDF]

open access: yes, 2017
We present a novel sun sensor concept. It is the very first sun sensor built with an address event representation spiking pixel matrix. Its pixels spike with a frequency proportional to illumination.

Linear-Logarithmic CMOS Image Sensor with Reduced FPN Using Photogate and Cascode MOSFET

open access: yesProceedings, 2017
We propose a linear-logarithmic CMOS image sensor with reduced fixed pattern noise (FPN). The proposed linear-logarithmic pixel based on a conventional 3-transistor active pixel sensor (APS) structure has additional circuits in which a photogate and a ...

Subthreshold Operation of Photodiode-Gated Transistors Enabling High-Gain Optical Sensing and Imaging Applications

open access: yesIEEE Journal of the Electron Devices Society, 2020
In optical sensors and imagers, high gain that leads to high sensitivity and high signal to noise ratio (SNR) is often desirable. One popular approach is avalanche photomultiplication initiated by impact ionization in an avalanche photodiode or similar ...

DDD17: End-To-End DAVIS Driving Dataset [PDF]

open access: yes, 2017
Event cameras, such as dynamic vision sensors (DVS), and dynamic and active-pixel vision sensors (DAVIS) can supplement other autonomous driving sensors by providing a concurrent stream of standard active pixel sensor (APS) images and DVS temporal ...

Modeling the Performance of Single-Bit and Multi-Bit Quanta Image Sensors

open access: yesIEEE Journal of the Electron Devices Society, 2013
Imaging performance metrics of single-bit and multi-bit photo-electron-counting quanta image sensors (QIS) are analyzed using Poisson arrival statistics. Signal and noise as a function of exposure are determined.

Influence of Satellite Sensor Pixel Size and Overpass Time on Undercounting of Cerrado/Savannah Landscape-Scale Fire Radiative Power (FRP): An Assessment Using the MODIS Airborne Simulator

open access: yesFire, 2020
The fire radiative power (FRP) of active fires (AFs) is routinely assessed with spaceborne sensors. MODIS is commonly used, and its 1 km nadir pixel size provides a minimum per-pixel FRP detection limit of ~5–8 MW, leading to undercounting of AF pixels ...

First bent wafer-scale sensor in truly-cylindrical geometry for the ALICE ITS3 detector [PDF]

open access: yesEPJ Web of Conferences, 2022
An upgrade of the three innermost layers of the ALICE ITS, intended to be installed during the LHC Long Shutdown 3, is under development. The detector concept foresees the usage of curved, wafer-scale Monolithic Active Pixel Sensors.

Lensfree on-chip microscopy over a wide field-of-view using pixel super-resolution. [PDF]

open access: yes, 2010
We demonstrate lensfree holographic microscopy on a chip to achieve approximately 0.6 microm spatial resolution corresponding to a numerical aperture of approximately 0.5 over a large field-of-view of approximately 24 mm2.
