Chen Wenjing is mainly engaged in optical information processing, and presided over a provincial basic research project and a horizontal project.

As the main researcher, he participated in the research of many national natural science funds and provincial and ministerial projects, published more than 30 papers in core journals and international conferences at home and abroad, and nearly 20 papers were retrieved by SCI and EI. Many papers are cited by SCI.

Winning record

In February 2004, he won the first prize of the Natural Science Award of the Ministry of Education; Doctoral thesis "Research on Theory and Application of Fourier Transform Profilometry" won the third prize of excellent doctoral thesis of Sichuan University in 2003; In 2003, he won the Young Key Teacher Award of Sichuan University.

academic achievement

Chen Wenjing put forward some effective methods and academic ideas in optical three-dimensional measurement, especially in Fourier transform profilometry, wavelet transform profilometry and phase unwrapping research, which effectively expanded the application scope of three-dimensional measurement and achieved some research results.

The selection of measurement range and sampling frequency based on discrete Fourier transform analysis, fast FTP of two-color fringe projection and some new technologies to eliminate spectral aliasing have greatly enriched the theory and practice of Fourier transform profilometry.

The reliable phase unwrapping method in wavelet transform profilometry, as well as its structural conditions and sampling condition criteria, laid the foundation for the further application of wavelet transform profilometry.
