RESEARCH

Institute of Optical Engineering

There are five Professors and five associate professors in the Institute of optical Engineering. Their research interests mainly focus on hybrid refractive/diffractive optical imaging, optical testing and instrumentation, color optics.

They have developed infrared refractive/diffractive optical systems and panoramic annular imaging systems, which have been used for pico-satellites. They have also developed several scientific instruments and systems, such as sparse micro-defects evaluation system for large optical components, Long focal-length measurment system, transient pulse laser diagnosing interferometers, high-speed flow field visualization system, solar-blind UV imaging systems, versatile sphere & aspheric interferometric testing systems, polarized micro-pulse lidar, etc. In addition, a high-performance LED lighting platform has been established to enable the adjustment of various lighting-quality parameters such as light shape, distribution, SPD, CCT, illuminance, CRI, etc. This institute has built up strong connection with leading international labs and industries. In the past five years, there are more than 100 scientific papers published and more than 20 patents issued.
