Real-time noise detection method and system for photon counting pixel array

The single photon counting sensor array includes: one or more emitters configured to emit a plurality of energy pulses; and a detector array including a plurality of pixels. Each pixel includes one or more detectors, a plurality of the one or more detectors configured to receive reflected energy pulses emitted by the one or more emitters. The mask material is positioned to cover part of the detectors of the plurality of pixels rather than all of the detectors to produce blocked pixels and unblocked pixels such that each blocked pixel is prevented from detecting reflected energy pulses so that each blocked pixel only detects intrinsic noise. 单光子计数传感器阵列包括：一个或多个发射器，被配置为发射多个能量脉冲；以及检测器阵列，该检测器阵列包括多个像素。每个像素包括一个或多于一个检测器，多个所述一个或多于一个检测器被配置为接收反射的、由一个或多个发射器发射的能量脉冲。掩膜材料被定位为覆盖多个像素的部分检测器而非全部检测器，以产生被阻挡的像素和未被阻挡的像素，使得防止每个被阻挡的像素检测反射的能量脉冲，从而每个被阻挡的像素只检测固有噪声。
