📋 论文概要

本文提出了一种异步160×90闪光LiDAR传感器，通过像素级飞行时间验证实现5至250fps的动态帧率，解决了传统闪光LiDAR中高光子通量管理和帧率固定的问题。

💡 主要创新点

• 提出像素级ToF验证机制，实现异步动态帧率调整，从5fps到250fps自适应变化。
• 采用异步架构减少冗余数据读出，降低功耗并提高帧率灵活性。

Sogang University, Seoul, Korea 1 2 Over the past few decades, LiDAR technology has become a cornerstone in various fields, including autonomous vehicles, augmented reality, and robotics. Unlike traditional scanning LiDAR systems, flash LiDAR technology captures the entire field of view in a single frame, enabling faster 3D mapping with fewer optical components. To manage the large influx of photons received by the sensor, on-chip histogramming time-to-digital converters (hTDC) are widely employed, facilitating time-correlated single-photon counting techniques [1-5]. However, their physical size imposes constraints on spatial resolution. Partial histogramming techniques [1-3] or shared hTDC architectures leveraging advanced 3D
