Nowadays a wide range of scientific applications require the detection of very weak and fast luminescence signals in the time domain. Single molecule spectroscopy, diffuse optical tomography, time-resolved emission spectra are only a few examples among them. Advanced time-correlated single photon counting, that relies on multidetector and multidimensional acquisition, reveals itself as a powerful technique to gather deeper insight into various photochemical and biological processes. In this paper we present a high-speed, high-linearity A/D acquisition board that is designed as a building block for a compact, low-cost, multidetector acquisition system for photon-timing experiments. The prototype has been experimentally tested and the results fully comply the goal design specifications.
如今，广泛的科学应用需要在时域中检测非常微弱且快速的发光信号。单分子光谱学、漫射光学层析成像、时间分辨发射光谱只是其中的几个例子。先进的时间相关单光子计数技术依赖于多探测器和多维采集，是深入了解各种光化学和生物过程的有力技术。在本文中，我们展示了一种高速、高线性的A/D采集板，它被设计为用于光子定时实验的紧凑、低成本多探测器采集系统的一个组件。该原型已通过实验测试，结果完全符合目标设计规格。
