In this webinar hosted by the Laser Systems Technical Group, Paul McManamon (Exciting Technology LLC, University of Dayton) will discuss the history of lidar development around the world. Dr. McManamon lived much of this history starting in the 60’s, shortly after the invention of the laser. Early on, CO2 became popular for coherent laser radar, and NdYag for laser range finders and designators. Laser diodes also became prominent, allowing a reliable and efficient method of pumping. Applications including wind sensing, navigation, terrain mapping, 2D and 3D imaging, and velocity detection then followed. For example, CO2 based navigation laser radar was deployed, but with the advent of GPS has become less popular.
In turn, Dr. McManamon’s talk will discuss direct detection laser radar for range finding, designation, and topographic mapping of Earth and extraterrestrial objects. It will also discuss coherent lidar for wind sensing and for synthetic aperture laser radar development. Putting it all together, this talk will end with a discussion on how lidar is now very prominent for autonomous vehicles, with a competition between ~900 nm and ~1500 nm lidars, and between coherent vs direct detection lidars.
