Multidetector photon statistics
Tadashi Aoki · Physical Review A · 1977
It is theoretically shown that detector quantum-noise-free measurement is feasible by a joint moment (JM) method which utilizes many photodetectors. The quantum/shot noise disappears in the statistical moments of JM photon counting. The statistical error in the JM measurement is calculated for light with Gaussian statistics and a Lorentzian spectrum and compared with that in the usual factorial moment method which utilizes a single photodetector. The JM measurement is shown to be useful for the measurement of very weak light with a wide spectrum.
