What Does a One-Bit Quanta Image Sensor Offer?

IEEE Transactions on Computational Imaging, 2022
The one-bit quanta image sensor (QIS) is a photon-counting device that captures image intensities using binary bits. Assuming that the analog voltage generated at the floating diffusion of the photodiode follows a Poisson-Gaussian distribution, the sensor produces either a ``1'' if the voltage is above a certain threshold or ``0'' if it is below the ...

Optimal Threshold Design for Quanta Image Sensor [PDF]

IEEE Transactions on Computational Imaging, 2018
Quanta Image Sensor (QIS) is a binary imaging device envisioned to be the next generation image sensor after CCD and CMOS. Equipped with a massive number of single photon detectors, the sensor has a threshold $q$ above which the number of arriving photons will trigger a binary response "1", or "0" otherwise.

CMOS Image Sensors and the Quanta Image Sensor

2018 International Conference on Optical MEMS and Nanophotonics (OMN), 2018
This paper briefly reviews CMOS image sensor invention and development. The focus of the paper is on a possible successor - the Quanta Image Sensor – a photon-counting image sensor that operates at room temperature without avalanche multiplication. Experimental results with 1Mpixel array devices are described.

Quanta image sensor: concepts and progress

SPIE Proceedings, 2016
The QIS was conceived when contemplating shrinking pixel sizes and storage capacities, and the steady increase in digital processing power. In the single-bit QIS, the output of each field is a binary bit plane, where each bit represents the presence or absence of at least one photoelectron in a photodetector. A series of bit planes is generated through

Progress status on Quanta Image Sensors

Photonics for Quantum 2020, 2021
The Quanta Image Sensor (QIS) is a photon-counting image sensor conceptualized in 2004 by Fossum and reduced to practice over the past 8 years at Dartmouth using a CMOS image sensor platform, and now referred to as CIS-QIS. This CIS-QIS device is a photon-number resolving sensor that does not use avalanche multiplication, and has been demonstrated in ...

A 2.5 pJ/b Binary Image Sensor as a Pathfinder for Quanta Image Sensors

IEEE Transactions on Electron Devices, 2016
This paper presents a pathfinder binary image sensor for exploring low-power dissipation needed for future implementation of gigajot single-bit quanta image sensor (QIS) devices. Using a charge-transfer amplifier design in the readout signal chain and pseudostatic clock gating units for row and column addressing, the 1-Mpixel binary image sensor ...

Jot devices and the Quanta Image Sensor

2014 IEEE International Electron Devices Meeting, 2014
The Quanta Image Sensor (QIS) concept and recent work on its associated jot device are discussed. A bipolar jot and a pump-gate jot are described. Both have been modelled in TCAD. As simulated, the pump-gate jot has a full well of 200e- and conversion gain of 480uV/e-.

Theoretical analysis and image reconstruction for multi-bit quanta image sensors

Signal Processing, 2021
Abstract A new breed of photon-counting sensors, called quanta image sensor (QIS), enables the detection of light with precision represented by the number of photons arriving within a time period. However, most existing analysis results on QIS systems are formulated for the single-bit case only.

Image reconstruction and threshold design for Quanta Image Sensors

2016 IEEE International Conference on Image Processing (ICIP), 2016
Quanta Image Sensor (QIS) has been envisioned as a candidate solution for next generation image sensors. We provide two new contributions to the signal processing aspects of QIS. First, we develop an image reconstruction algorithm to recover the underlying images from the QIS data, which is a massive array of binarized Poisson random variables. The new

Enabling Low-light Digital Holography with a Quanta Image Sensor

Digital Holography and 3-D Imaging 2022, 2022
We demonstrate a digital holographic imaging system where the hologram is captured by a quanta image sensor (QIS), and the object wavefront is then computationally retrieved. This scheme enables digital holography at a very low signal level via individual photon detection.
