Abstract

A system for sterilizing at least one surface of an object is provided. The system includes a set of ultraviolet radiation sources and a set of wave guiding structures configured to direct ultraviolet radiation having a set of target attributes to a desired location on at least one surface of the object. The set of wave guiding structures can include at least one ultraviolet reflective surface having an ultraviolet reflection coefficient of at least thirty percent. Furthermore, the system can include a computer system for operating the ultraviolet radiation sources to deliver a target dose of ultraviolet radiation to the at least one target surface of the object.
