主动深度成像方法在包括环境传感、制造和国防在内的许多学科中都有许多潜在的应用。单光子计数技术的高灵敏度和皮秒计时分辨率可以在所需照明功率，范围，深度分辨率和数据采集持续时间之间的权衡中提供明显的优势。这些考虑还必须满足眼睛安全的要求，特别是在需要户外、公里范围传感的应用中。我们提出了一种基于高重复率（>MHz）脉冲照明和硅单光子探测器的扫描飞行时间成像仪。在先进的光子计数实验中，我们已经使用该系统在几公里的目标距离上进行了明确的距离分辨率，基于自适应算法的多表面分辨率，以及有助于探测器表征和评估的累积数据采集方法。我们考虑了一系列光学设计配置，并更详细地讨论了性能权衡。为了方便使用硅基单光子雪崩二极管探测器，大部分工作都是在波长约850nm下进行的，但是我们也将讨论使用超导纳米线单光子探测器在波长约1550 nm下的性能。将这种深度剖析技术扩展到更长的波长将导致眼睛安全要求的放松，降低太阳背景水平和改善大气传输。
Active depth imaging approaches have numerous potential applications in a number of disciplines, including environmental sensing, manufacturing and defense. The high sensitivity and picosecond timing resolution of the singlephoton counting technique can provide distinct advantages in the trade-offs between required illumination power, range, depth resolution, and data acquisition durations. These considerations must also address requirements for eye-safety, especially in applications requiring outdoor, kilometer range sensing. We present a scanning time-of-flight imager based on high repetition-rate (>MHz) pulsed illumination and a silicon single-photon detector. In advanced photon-counting experiments, we have employed the system for unambiguous range resolution at several kilometer target distance, multiple-surface resolution based on adaptive algorithms, and a cumulative data acquisition method that facilitates detector characterization and evaluation. We consider a range of optical design configurations and discuss the performance trade-offs in more detail. Much of this work has been performed at wavelengths around 850nm for convenient use with Si-based single photon avalanche diode detectors, however we will also discuss the performance at wavelengths around 1550 nm employing superconducting nanowire single photon detectors. The extension of this depth profiling technique to longer wavelengths will lead to relaxed eye safety requirements, reduced solar background levels and improvements in atmospheric transmission.
