Smart CMOS image sensor for lightning detection and imaging [PDF]
Applied Optics, 2013 We present a CMOS image sensor dedicated to lightning detection and imaging. The detector has been designed to evaluate the potentiality of an on-chip lightning detection solution based on a smart sensor. This evaluation is performed in the frame of the predevelopment phase of the lightning detector that will be implemented in the Meteosat Third ...

Single-Event Effects in CMOS Image Sensors [PDF]
IEEE Transactions on Nuclear Science, 2013 In this paper, 3T active pixel sensors (APS) are exposed to heavy ions (N, Ar, Kr, Xe), and single-event effects (SEE) are studied. Devices were fully functional during exposure, no single-event latch-up (SEL) or single-event functional interrupt (SEFI) happened.

On Evolution of CMOS Image Sensors [PDF]
International Journal on Smart Sensing and Intelligent Systems, 2014 Abstract CMOS Image Sensors have become the principal technology in majority of digital cameras. They started replacing the film and Charge Coupled Devices in the last decade with the promise of lower cost, lower power requirement, higher integration and the potential of focal plane processing.

CMOS image sensor for spatiotemporal image acquisition [PDF]
Journal of Electronic Imaging, 2006 We present a 64-×64-pixel CMOS image sensor chip that can acquire a 16-gray-level image containing both spatial and temporal information of the moving luminous object under observation. The image can next be processed using any image processing software in order to determine the speed, trajectory, and direction of motion of the moving object.

DENOISING ALGORITHM FOR THE PIXEL-RESPONSE NON-UNIFORMITY CORRECTION OF A SCIENTIFIC CMOS UNDER LOW LIGHT CONDITIONS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 We present a denoising algorithm for the pixel-response non-uniformity correction of a scientific complementary metal–oxide–semiconductor (CMOS) image sensor, which captures images under extremely low-light conditions. By analyzing the integrating sphere
