lidar
Lidar functions as a technical term describing a specific light-based detection technology. It carries a connotation of precision and high-tech sophistication, typically appearing in scientific, engineering, or autonomous vehicle contexts. While radar uses radio waves, lidar is distinguished by its use of laser light, allowing for much finer spatial resolution and the creation of detailed 3D point clouds.
As a mass noun referring to a technology or a method, it is generally treated as uncountable. It describes the system or the process of sensing rather than individual units of equipment, which are typically referred to as lidar sensors or lidar systems.
