The Quanta Image Sensor: Every Photon Counts
The Quanta Image Sensor (QIS) was conceived when contemplating shrinking pixel sizes and storage capacities, and the steady increase in digital processing power. In the single-bit QIS, the output of each field is a binary bit plane, where each bit represents the presence or absence of at least one photoelectron in a photodetector. A series of bit planes is generated through high-speed readout, ...

متن کاملQuantum Random Number Generation Using a Quanta Image Sensor
A new quantum random number generation method is proposed. The method is based on the randomness of the photon emission process and the single photon counting capability of the Quanta Image Sensor (QIS). It has the potential to generate high-quality random numbers with remarkable data output rate. In this paper, the principle of photon statistics and theory of entropy are discussed. Sample data...
متن کاملApplication of Photon Statistics to the Quanta Image Sensor
The Poisson statistics of photon arrival rates are applied to the imaging performance of the Quanta Image Sensor (QIS) concept. Signal and noise as a function of exposure is analyzed and we find SNR only obeys the square-root law under sparse exposure. The Dlog H characteristic of the QIS is quantified. Linearity and dynamic range are also investigated. I. SIGNAL Photons are emitted from light ...
متن کاملGeometric methods for optimal sensor design
The Kalman-Bucy filter is the optimal estimator of the state of a linear dynamical system from sensor measurements. Because its performance is limited by the sensors to which it is paired, it is natural to seek optimal sensors. The resulting optimization problem is however non-convex. Therefore, many ad hoc methods have been used over the years to design sensors in fields ranging from engineeri...
