A sensor for assessing the quality of the mineral flotation process
(IEEE, 1994)
An instrument to assess the quality of the flotation process for mineral concentration in the copper industry has been developed. It is based on computer processing of images of the foam formed at the surface of flotation ...

Smart Readout of Nondestructive Image Sensors with Single Photon-Electron Sensitivity
(American Physical Society, 2021-12)
Image sensors with nondestructive charge readout provide single-photon or single-electron sensitivity, but at the cost of long readout times. We present a smart readout technique to allow the use of these sensors in visible ...
