Nanjing University 5D Technology Co.,Ltd is the national high-tech enterprise which dedicated to the research and industrialization of advanced Photonics and IoT Sensor technology.We first time built solar blind ultraviolet imaging technology,which has been widely used in corona inspection of the power grid and high-speed railway, aircraft landing and ship navigation under low-visibility atmospheric conditions. We first established the quantified evaluation theory detectors and imagers of the ultraviolet. Also, we drafted the industrial standard of the ultraviolet imager with the High voltage committee of State Grid Corporation of China.
