Abstract

Imaging performance metrics of single-bit and multi-bit photo-electron-counting quanta image sensors (QIS) are analyzed using Poisson arrival statistics. Signal and noise as a function of exposure are determined. The D-log H characteristic of single-bit sensors including overexposure latitude is quantified. Linearity and dynamic range are also investigated. Read-noise-induced bit-error rate is analyzed and a read-noise target of less than 0.15 e-rms is suggested.
