3D-Stacked CMOS SPAD Image Sensors: Technology and Applications
International Conference on Electronics, Circuits, and Systems, 20183D-stacked CMOS SPAD based image sensors hold the promise for better sensitivity and more functionality per pixel. The technology enables to separate detection from computation onto different chips, or tiers, that are stacked onto one another.

Computational image sensor for on sensor compression
IEEE Transactions on Electron Devices, 1997In this paper, we propose novel image sensors which compress image signal. By making use of very fast analog processing on the imager plane, the compression sensor can significantly reduce the amount of pixel data output from the sensor. The proposed sensor is intended to overcome the communication bottle neck for high pixel rate imaging such as high ...

Phase imaging using shifted wavefront sensor images
Optics Letters, 2014We propose a new approach to the complete retrieval of a coherent field (amplitude and phase) using the same hardware configuration as a Shack-Hartmann sensor but with two modifications: first, we add a transversally shifted measurement to resolve ambiguities in the measured phase; and second, we employ factored form descent (FFD), an inverse algorithm

Sensors and Actuators, 1986
After a short treatment of the basic principles involved in visible-light image sensors the factors determining resolution, sensitivity and dynamic range are discussed. Recent improvements in XY-addressed, interline and frame transfer sensors are presented to demonstrate the versatility of design and technology.

IEEE Journal of Solid-State Circuits, 1970
The development and evaluation of a germanium imaging sensor is described. The sensor, comprised of an electron-beam-scanned photodiode array, was designed for air-glow operation. Surface- barrier photodiode arrays were developed for optimized imaging, and their processing provided a powerful technique for preserving the characteristic properties of ...

Current Opinion in Chemical Biology, 2002
Imaging optical fibres have been etched to prepare microwell arrays. These microwells have been loaded with sensing materials such as bead-based sensors and living cells to create high-density sensor arrays. The extremely small sizes and volumes of the wells enable high sensitivity and high information content sensing capabilities.

Magnetic Resonance Imaging, 2003
A portable single sided sensor to render depth profiles of MR signal non-invasively is presented. The device utilizes a tailored permanent magnet array producing flat sensitive volumes up to 40 mm from the mobile inspection head. Automated slice selection is performed using a set of switched capacitors in the tuning and receiver circuits.
