METHODS AND SYSTEMS FOR STERILIZING SPACES OR SURFACES FROM STAND-OFF DISTANCES

摘要

A method, system, and apparatus of sterilizing or disinfecting a space or surface with UV light from a laser that produces UV or other light energy with germicidal effect, at least like UVGI. The light can be controlled in terms of power to be effective for germicidal effect on a given biological organism or agent. In cases where humans might be present and represent a risk of interaction with the laser, techniques are used to remove those risks. The laser can be directed to a single relatively small area, aimed to multiple areas, or scanned to cover larger areas. It allows either human operation at stand-off distances from the relevant spaces, volumes, areas, surfaces (e.g., at least inches and typically feet or tens of feet). It has an indefinite useful operation life.
