Researchers have developed a program for outputting high-quality freeform optical systems that simply requires basic optical design knowledge
Current worldwide conditions have brought a renewed focus on ultraviolet or UV based sterilization systems. UV light has been shown to kill many types of pathogens. A key metric is the dose, or amount of UV light on a surface, as a minimum dosage level is required for effective sterilization. Using optical analysis software as part of the design process ensures that these minimum dosage levels are obtained.
This paper presents the most up to date compilation of research and data available in the literature regarding the optical properties of human tissue. The relevant optical, biological, and measurement details are presented to illustrate the necessary considerations that should be observed when modeling human tissue in LightTools. It also describes how this information has been incorporated into a new Human Tissue Utility. This utility aims to take some of the guesswork out of creating User Materials that model biological tissues.
