SPAD Single-Photon Detection
Gated-Mode Analysis
Effective background noise in gated operation, from gate width, repetition rate and raw noise.
N_eff = N_raw · (Width · Freq)
Fill the inputs from a real part
Every number is read from that part's datasheet entry: peak power and pulse energy as rated, pulse width at the part's rated maximum.
