Detection system based on a novel large area hybrid detector
TL;DR: The proposed solution relies on a stack of interconnection layers, deposited on top of the photodiode array, to route each individual pixel output to a separate pre-amplifier channel, which avoids the need for a geometrical matching between the sensor array and the chip contact pads.

Reduction of photon shot noise using M-transform
TL;DR: In this paper, the photon shot noise is converted into small amplitude signals and then the signals are treated to remove the small amplitude noise by an e-filter and the edge of the object is protected by not treating the e filter into the detect edge.

Active Pixel Sensors: Are CCD's Dinosaurs?
TL;DR: ActivePixel Sensor (APS) as mentioned in this paper is a detector array technology that has at least one active transistor within the pixel unit cell, which eliminates the need for nearly perfect charge transfer, which makes CCD's radiation'soft' and difficult to use under low light conditions, difficult to integrate with on-chip electronics, difficulty to use at low temperatures, and difficulty to manufacture in non-silicon materials that extend wavelength response.
