Researchers Use Gated Digital Holography Methods to Develop Foliage-Penetrating LiDAR System

摘要

Shortly after lasers were first developed in the 1960s, LiDAR - whose name originated as a combination of "light" and "radar" - capitalized on the newly unique precision they offered for measuring both time and distance. LiDAR quickly became the standard method for (3-D) land surveys and is now used in a multitude of sensing applications, such as self-driving cars.
