-Signal Sensing & Processing Architectures • Main sensing and read-out micro-circuit elements > in-pixel conversion of charge into electrical signal (e.g.voltage) with average noise subtraction

Digital Focal Plane Array Technology: The Digital Focal Plane Array developed at MIT overcomes the limitations of traditional FPAs by performing in-pixel signal digitization. By doing this it enables larger dynamic range, faster low-noise all digital readout and on-chip processing. An example unit cell can be seen in Figure 3 below.

Pixel Array Click and drag the mouse up and down to control the signal and press and hold any key to see the current pixel being read. This program sequentially reads the color of every pixel of an image and displays this color to fill the window.

tor array with a digital-pixel readout integrated circuit (DROIC) designed by Lincoln Laboratory; this compat-Lincoln Laboratory has developed a digital-pixel focal plane array with per-pixel, 16-bit full dynamic range, analog-to-digital conversion, and real-time digital image processing capability. The technology leverages modern semiconductor

A field-programmable smart-pixel array ~FP-SPA! is a smart-pixel array capable of having its electronic functionality dynamically programmed in the field. Such devices could be used in a diverse range of applications, including optical switching, optical digital signal processing, and optical image processing. We describe the design, VLSI im-

Pixel level processing promises many significant advantages including high SNR, low power, and the ability to adapt image capture and processing to different environments by processing signals during integration. However, the severe limitation on pixel size has precluded its mainstream use.

Sep 1, 2020 · While the image processing in most of the conventional analog and digital ROICs is performed off-chip, using Digital Signal Processors (DSPs) or Field Programmable Gate Arrays (FPGAs), the proposed solution advocates the use of on-chip image processing.

May 5, 2014 · A digital pixel CMOS focal plane array has been developed to enable low latency implementations of image processing systems such as centroid trackers, Shack-Hartman wavefront sensors, and Fitts correlation trackers through the use of in-pixel digital signal processing (DSP) and generic parallel pipelined multiply accumulate (MAC) units.
