PORTABLE SANITIZATION SYSTEM AND METHOD WITH ULTRAVIOLET AND VISIBLE LIGHT SENSING

Abstract:

A system and method for sanitizing a surface within an aircraft includes emitting UV radiation from a UV radiation source toward the surface, and emitting visible light from a visible light source toward the surface. A UV sensor senses an intensity of the UV radiation reflected by a reflector that is disposed on a least a portion of the surface and a visible light senses an intensity of the visible light reflected by the reflector. A processor processes the UV intensity signal and the visible light intensity signal to determine the intensity of the UV radiation on the surface and a UV dose to the surface.
