Understanding LiDAR Design: Foundational Principles and Reference Designs
LiDAR, or Light Detection And Ranging, is the practice of using light or non-visible electromagnetic radiation to detect and measure distance to objects. Used in everything from agriculture to meteorology, biology to robotics, and law enforcement to solar photovoltaics deployment, LiDAR can image small things like historic relics for archaeology or people-counting applications at the entrance of a building. On the other end of the spectrum, LiDAR can also image very large things like landscapes for agriculture and geology.
Then you have LiDAR systems that image moving objects or may be moving, themselves. These nonstatic systems may become the most common form of LiDAR as they are used for machine vision in military systems, survey aircraft, and prototype autonomous cars. Yet other forms of LiDAR are not used to image solid surfaces at all: NASA uses LiDAR in atmospheric research while other LiDAR systems are designed to function and image surfaces underwater.
