Abstract: A radiation-based disinfection system with detectors and an intelligent controller is capable of disinfecting small areas on surfaces with a suitable light source (e.g. a UV laser) in a dynamic fashion in high traffic environments while avoiding vulnerable targets with incident or reflected beams. The disinfection system operates by predicting likely 5 transmission sites between potential sources of infection and other objects in the environment.

Abstract: A method and system for disinfecting a volume in space involves: localizing a volume in space requiring disinfection; calculating directions to the volume in space from a plurality of available beam-producing light sources for disinfection and projecting at least one light beam from the available beam-producing light sources to the volume in space; and, coordinating the projected light beams to minimize time required to deliver a threshold disinfecting light dose to the volume in space requiring disinfection.
