WebJul 1, 2015 · The “effective dark count rate” is usually defined as an inverse value of the mean time elapsed between detector activation (gating ON) and the registration of the avalanche breakdown. The effective dark count rate of K14 series SPAD chip depends on temperature, detector active area and gate. WebAt high counts the shot-noise limit (α=0.9) and at low counts the read noise limit (n read =30 counts) It is instructive to plot the SNR versus the signal level in counts on a double logarithmic scale as this clear shows the two limiting cases – the shot noise limit and the read noise limit. The plotted relationship is.
