论文摘要
我们报告了基于线扫描架构的时间分辨单光子计数（TCSPC）成像系统。该系统受益于高级CMOS单光子雪崩二极管（SPAD）阵列线传感器的高填充因子，活动区域和大尺寸。使用移动镜构建了二维图像，以扫描跨目标的线传感器视野（FOV），以便有效获取二维0.26 Mpixel TCSPC图像。我们演示了系统对TCSPC成像的功能，并定位在散射介质中遮盖的物体 - 特别是在高度散射溶液中沿光纤沿光纤沿光纤定位一系列离散点的光源。我们证明，通过使用早期到达的光子进行选择性成像，比以后的光子进行散射少的光子，我们的TCSPC成像系统能够找到光的离散点源的位置，而不是非时代分辨成像系统。
We report a time-resolved single photon counting (TCSPC) imaging system based on a line-scanning architecture. The system benefits from the high fill-factor, active area, and large dimension of an advanced CMOS single photon avalanche diode (SPAD) array line-sensor. A two-dimensional image is constructed using a moving mirror to scan the line-sensor field-of-view (FOV) across the target, to enable the efficient acquisition of a two-dimensional 0.26 Mpixel TCSPC image. We demonstrate the capabilities of the system for TCSPC imaging and locating objects obscured in scattering media - specifically to locate a series of discrete point sources of light along an optical fibre submerged in a highly scattering solution. We demonstrate that by selectively imaging using early arriving photons which have undergone less scattering than later arriving photons, our TCSPC imaging system is able to locate the position of discrete point sources of light than a non-time-resolved imaging system.
