Abstract

We present a Montecarlo simulator developed in Matlab for the analysis of a Single Photon Avalanche Diode (SPAD)-based Complementary Metal-Oxide Semiconductor (CMOS) flash Light Detection and Ranging (LIDAR) system. The simulation environment has been developed to accurately model the components of a flash LIDAR system, such as illumination source, optics, and the architecture of the designated SPAD-based CMOS image sensor. Together with the modeling of the background noise and target topology, all of the fundamental factors that are involved in a typical LIDAR acquisition system have been included in order to predict the achievable system performance and verified with an existing sensor.

摘要

我们展示了一个在Matlab中开发的蒙特卡罗模拟器，用于分析基于单光子雪崩二极管（SPAD）的互补金属氧化物半导体（CMOS）闪光光探测与测距（LIDAR）系统。已开发出该模拟环境，以精确模拟闪光LIDAR系统的组件，如照明源、光学器件以及指定的基于SPAD的CMOS图像传感器的架构。连同背景噪声和目标拓扑结构的建模，典型LIDAR采集系统中涉及的所有基本因素都已包含在内，以便预测可实现的系统性能，并通过现有传感器进行验证。
