本文提出了一款64×64像素的数字硅光电倍增管直接飞行时间传感器，应用于航天器导航的闪光激光雷达。该传感器实现了每像素每秒1亿光子的背景抑制能力，解决了在强背景光下进行精确距离成像的问题。
Recent technology surveys identified flash light detection and ranging technology as the best choice for the navigation and landing of spacecrafts in extraplanetary missions, working from single-point altimeter to range-imaging camera mode. Among all available technologies for a 2D array of direct time-of-flight (DTOF) pixels, CMOS single-photon avalanche diodes (SPADs) represent the ideal candidate due to their rugged design and electronics integration. However, stateof-the-art SPAD imagers are not designed for operation over a wide variety of scenarios, including variable background light, very long to short range, or fast relative movement. A typical DTOF imager consists of a per-pixel time-to-digital converter (TDC) capturing the timestamp of the first detected photon [1]. However, in presence of background light, high dark-count rate (DCR), or long observation time, the probability of catching an unwanted event instead of the light echo becomes very
