通过使用在多重散射光中编码的飞行时间信息，可以重建从相机的直接视线隐藏的物体的图像。在这里，我们提出了一个非视线成像系统，使用单像素，单光子雪崩二极管（SPAD）收集飞行时间信息。与早期的系统相比，这种修改在功率要求、形状因子、成本和重建时间方面提供了显著的改进，同时保持了相当的时间分辨率。该技术进一步减小尺寸和降低成本的潜力使该系统成为开发可用于真实的世界应用的实用系统的良好基础。(C)2015美国光学学会
By using time-of-flight information encoded in multiply scattered light, it is possible to reconstruct images of objects hidden from the camera's direct line of sight. Here, we present a non-line-of-sight imaging system that uses a single-pixel, single-photon avalanche diode (SPAD) to collect time-of-flight information. Compared to earlier systems, this modification provides significant improvements in terms of power requirements, form factor, cost, and reconstruction time, while maintaining a comparable time resolution. The potential for further size and cost reduction of this technology make this system a good base for developing a practical system that can be used in real world applications.
