    During the past five years, I work on two areas for fulfilling requirements on precision and intelligence of advanced manufacturing, they are, precision metrology & instruments and intelligent production technologies & equipment. Six platforms are constructed, including holographic lithography enabled advanced grating fabrication, grating interferometry, chromatic confocal sensing, rapid and precision structured light enabled 3D reconstruction, SLAM for AGV, and artificial intelligence (AI) based automatic optical inspection (AOI). More than 60 peer-reviewed articles and proceedings about abovementioned areas were published, more than 20 patents were filed/granted, research fundings with a total amount of more than 15 million RMB were granted for supporting on platform construction, students training as well as technicians recruitment. There are 21 members graduating from or worked in my group, they are, 1 post-doctor, 2 doctors, 18 masters.

    Contributions of my research group can be categorized into six directions. Firstly, polarization manipulation enabled holographic lithography technique firstly proposed in my group allows fabrication of large area micro-nano structure array with high uniformity and periodic tunability, which greatly benefits today’s nano science and technology. Secondly, a hybrid planar grating with mixed coding firstly developed in my group brings an outstanding grating interferometric solution that owns advantages on multi-DOF, sub-nanometric, absolute and large stroke simultaneously. This is a proven prior choice for the most advanced positioning solution for lithography machine. Thirdly, in the chromatic confocal area, we completely solved the problem caused by reflectance variation of target surface and spectrum distribution imperfection existing in the light source by using a modified interpolation optical configuration and a self-reference strategy. Fourth, aiming for improvement of intelligence and flexibility in production process, we developed SLAM based AGV with sensing integration of vision, points cloud by Lidar and initial guiding IMU unit. Fifth, we proposed high precision target reconstruction via FPGA controlled MEMS mirror structured light system for a highly reliable and dynamic detection and positioning for various industrial robots. Lastly, we focused on transfer learning and deep learning techniques for highly efficient and accurate AOI application for many industrial situations. These outbreaking innovations and integration applications have been being employed in and are playing a significant role on advanced manufacturing of China.
