基于单光子探测器阵列的抗噪声频域成像研究
Noise-resistant frequency-domain imaging based on single-photon detector arrays
摘要
Abstract
Due to the high single-photon detection sensitivity and the characteristics of multiple pixels,single-photon detector arrays(SPDA)have been widely applied in the areas of single-photon radar,bioluminescence imaging,and so on.However,limited by fabrication technology,the photon detection efficiency of each pixel of SPDA presents a certain difference,which often leads to imaging distortion.To solve this problem,the reverse bias voltage of each single photon detector for a 4×4 SPDA has been optimized individually in this work,which increases the averaged photon detector efficiency by 1.77 folds and reduces the difference to 1/7 of that before adjustment.Then on this basis,a Fourier-domain imaging(FDI)scheme has been developed by performing Fourier transform on the photon arriving time of each single-photon detector and using Fourier transform amplitude as the imaging parameter.The results show that with FDI scheme,a reasonably good imaging with a contrast-to-noise ratio up to 2.29 can still be determined even under the condition that the ratio of the noise intensity to the signal intensity reaches 104,manifesting the strong noise-resistant feature of FDI.This work offers a new route for achieving single photon detector under complex and noisy environments based on SPDA.关键词
