Dynamic range extension for photon counting arrays

Express, vol. 26, no. 17, p. 22234-22248, Aug. 2018. The first three sections output the F factor described in the paper.

The fourth section plots the theoretical response, standard deviation and signal-to-noise ratio for the three recharge mechanisms. Measured and detected counts are denoted with m and n, respectively, and normalized to 1/Tdead, where Tdead is the dead time of SPAD imagers. When following the Quanta Image Sensor notation, m/Tdead is the bit density D or electrons, and n/Tdead is the exposure H. The fifth section verifies the theoretical curves with simulations results, which are plotted in the last section of the script.
