Abstract

A heterodyne detection mechanism with Geiger-mode avalanche photodiode detector arrays is proposed for optical systems to achieve high sensitivity and good anti-interference. In contrast to the conventional processing method of photon arrival sequence, where the step of incoherent accumulation is canceled, the beat frequency is only obtained in this paper by the coherent superposition of phase-matched sequences, which can alleviate or even reduce the effect of the initial phase drift between the frames of the beat frequency signal. After phase matching of the beat signal, the power spectral density intensity of coherent superposition is greater than that of incoherent accumulation.
