New advances in the field of image sensors (especially in CMOS technology) tend to question the conventional methods used to acquire the image. Compressive Sensing (CS) plays a major role in this, especially to unclog the Analog to Digital Converters which ...
This paper explores a new way to reduce the readout noise for CMOS image sensors by using a typical 4T pixel embedding a PMOS source follower with reduced oxide thickness and gate dimensions. This approach is confirmed by a test chip designed in a 180 nm C ...
In this paper, an analytical noise calculation is presented to derive the impact of process and design parameters on 1/f and thermal noise for a low-noise CMOS image sensor (CIS) readout chain. It is shown that dramatic noise reduction is obtained by using ...

LinoSPAD is a reconfigurable camera sensor with a 256x 1 CMOS SPAD (single-photon avalanche diode) pixel array connected to a low cost Xilinx Spartan 6 FPGA. The LinoSPAD sensor's line of pixels has a pitch of 24 pm and 40% fill factor. The FPGA implements ...
Since the first introduction of digital cameras, the camera market has been taking tremendous interest from many fields. This trend has even accelerated when the cost, size, and power consumption of such devices were reduced with the introduction of camera ...
A method of acquiring an image of a scene illuminated by a first beam, by means of a sensor including at least two pixels, including the steps of: a) for each pixel, reading a first output value of the pixel representative of the intensity of the radiation ...
Event-based dynamic vision sensors (DVSs) asynchronously report log intensity changes. Their high dynamic range, sub-ms latency and sparse output make them useful in applications such as robotics and real-time tracking. However they discard absolute intens ...
In recent years, modern imaging sensors and systems have become increasingly complex following the growing demand for high-quality and high-resolution imaging. Commercially available sensors having 30-40 mega-pixel resolutions are common nowadays, while pr ...
We report on high-field terahertz transients with 0.9-mJ pulse energy produced in a 400 mm(2) partitioned organic crystal by optical rectification of a 30-mJ laser pulse centered at 1.25 mu m wavelength. The phase-locked single-cycle terahertz pulses cover ...
A Digital Pixel Sensor (DPS) based CMOS camera configured to record frames and comprising an event detection sensor configured to look for an event happening in a determined frame, comprising an array of event detection pixels, a first reference voltage ge ...
