利用多像素光子计数器的光学串话效应提高光子探测效率
Increasing the photon detection efficiency by the optical crosstalk effect of multi-pixel photon counter
摘要
Abstract
This paper proposes that the photon detection efficiency( PDE) of Multi-Pixel Photon Counter( MP-PC) can be improved by the optical crosstalk( OC) effect when taking the output amplitude or output charge of the avalanche pulses as the parameter of photon counting through analyzing the operating principle and charac-teristics of the MPPC.The influence of the optical crosstalk effect on the photon detection efficiency is ana-lyzed.The theoretical results show that the photon detection efficiency increases significantly by the optical crosstalk effect of the MPPC under these photon counting modes.According to the results calculated by our model, the equivalent photon detection efficiency taking the OC effect into account is increased by about 50%,(i.e.:reaching 45%), if the total avalanche pixel number of MPPC is 1 600, the photon detection ef-ficiency regardless of the OC effect is 30%, the OC probability is 50%and the mean photon number is 10 per light pulse.This result is significant in the application of low light level detection such as astrophysics, parti-cle physics, and fluorescence spectroscopy.关键词
