OPTICAL FEEDBACK BASED CIRCUIT FOR IMPROVED STABILITY OF AN ULTBAVIOLET LIGHT SOUBCE

摘要

In recent years, increasing importance has been attached to the study of ultraviolet (UV) light, especially for improving measurement accuracy, but also in food safety, drug testing, environmental monitoring, climate study, Earth observation and space exploration among many other applications. With the development of technology processes such as photoetching and nanometrology, research has honed in on UV radiation and sources of UV light used in those applications, with a particular focus on improving a UV light source's output stability and eliminating noise.
