The Institute of Opto-electronic Engineering (IOEE) was established in 1958. It obtained the Chinese government's authorization to offer PhD program in 1981 and the approval to build the post-doctoral research site in 1988. The research of the IOEE covers opto-electronic instruments, precision metrology and measurement, modern optical information processing, the theory and components of binary optics, and the birefringent frequency-splitting lasers. Several famous scientists work in the IOEE, including Professor Guofan Jin, an academician of the Chinese Academy of Engineering, and Professor Kegong zhao, formerly the president of the Chinese National Institute of Metrology.
