Preface

The International Conference on Advanced Optics & Photonics Research in Engineering (AOPR 2021) (http://www.aopr-conf.com/) held from November 13-14, 2021 in Wuhan, China. Aiming at providing an excellent international academic forum for all the researchers and practitioners, the conference enjoys a wide spread participation among all over the universities and research institutes. It was provide opportunities for the delegates to exchange new ideas and application experiences, to establish business or research relations and to find global partners for future collaboration. Papers and topic concentrates on related fields of Optics and photonics are presented. AOPR 2021 proceeding tends to collect the most up-to-date, comprehensive, and worldwide state-of-art knowledge on Advanced Optics & Photonics Research in Engineering and other related topics. All the accepted papers have been submitted to strict peer-review by 2-3 international expert referees, and selected based on originality, significance and clarity for the purpose of the conference. The conference program is extremely rich, profound and featuring high-impact presentations of selected papers and additional late-breaking contributions. I sincerely hope that the conference would not only show the participants a broad overview of the latest research results on related fields, but also provide them with a significant platform for academic connection and exchange. The Technical Program Committee members have been working very hard to meet the deadline of review. The final conference received over 75 submissions, and 28 papers have been accepted. I would like to express our sincere gratitude to all the keynote speakers, editors, TPC members and organizers for their hard work, precious time and endeavor preparing for the conference. Our deepest thanks also go to the volunteers and staffs for their long-hours work and generosity they’ve given to the conference. The last but not least, we would like to thank each and every of the authors, speakers and participants for their great contributions to the success of AOPR 2021.
