主动三维远程成像在许多学科中有着不同的应用,包括制造、环境传感和国防。常见的限制通常包括低平均和峰值照明功率,以确保眼睛安全,使单光子计数技术的潜在高灵敏度成为一个明显的优势。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,我们最近采用的系统在几公里的目标距离,多表面分辨率的基础上自适应算法,和累积的数据采集方法,方便探测器的特性和评估的明确的距离分辨率。本文回顾了这些成就,并确定多光谱成像作为一个可能的未来应用。
Active, three-dimensional long-range imaging has varied applications in a number of disciplines, including manufacturing, environmental sensing and defence. Common constraints often include low average and peak illumination powers to ensure eye-safety, making the potentially high sensitivity of the single-photon counting technique a distinct advantage. 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 recently employed the system for unambiguous range resolution at several kilometres target distance, multiple-surface resolution based on adaptive algorithms, and a cumulative data acquisition method that facilitates detector characterisation and evaluation. This article reviews these achievements and identifies multi-spectral imaging as a possible future application.
