Abstract
A solution for disinfecting an ultraviolet transparent structure and/or an item placed on or near the structure is provided. The solution can utilize a set of ultraviolet radiation sources configured to generate ultraviolet radiation through the internal surface of the ultraviolet transparent structure towards the external surface and out to an ambient environment for disinfection of the external surface and/or a targeted item. A first set of sources can generate a scattered type of radiation that uniformly disinfects the external surface of the ultraviolet transparent structure and a second set of sources can generate a focused type of radiation that disinfects at least one portion of the targeted item. A control system can direct the first set of sources to generate the scattered radiation towards the external surface of the ultraviolet transparent structure and direct the second set of sources to generate the focused radiation at the targeted item.
