摘要

基于320×240单光子雪崩二极管(SPAD)的单光子计数图像传感器在0.13μm成像CMOS中实现，其像素间距为8μm，填充系数为26.8%。该成像仪被演示为全局快门(GS)过采样二进制图像传感器，读取速度为5.14kFPS。在FPGA上实时积累帧，以20FPS的速度构建256光子/8bit的输出图像。

320×240 oversampled digital single photon counting image sensor

A 320×240 single photon avalanche diode (SPAD) based single photon counting image sensor is implemented in 0.13μm imaging CMOS with state of the art 8μm pixel pitch at 26.8% fill factor. The imager is demonstrated operating as a global shutter (GS) oversampled binary image sensor reading out at 5.14kFPS. Frames are accumulated in real time on FPGA to construct a 256 photon/8bit output image at 20FPS.
