1 Introduction

Time-of-Flight is regarded as a very accurate distance mapping technology that has been used for over a century. ToF systems can be found in a wide variety of products, from proximity sensors, drone vision, machine vision, to automotive ADAS LiDAR systems. As seen with this system variety, ToF technology can calculate distances from just a few millimeters to several meters, have different field of views, power requirements, solution sizes, and different resolutions depending on the components used within the system. While there are different mediums to calculate distance in a ToF system such as ultrasonic or radar, this tech note will focus primarily on optical ToF systems.
