The simulated counter rate as a function of photon flux with T = 10 s and τ = 100 ns. Both counters C0 and C1 (corresponding to thresholds of ½ and [{3 \over 2}], respectively) have a complex dependency on the actual photon rate λ and deviate considerably from the ideal response (blue dashed line). When 2λτ exceeds 1 (corresponding to 5 M counts per pixel per second), the circuit is driven into saturation, resulting in counting paralysis. Note that using a single counter results in two different photon fluxes corresponding to a single counter value; using a second counter solves the confusion and effectively doubles the useful range.
