[Reporter Yang Mianjie/Taipei Report] Taiwanese students show top abilities!

The Taipei Technological University team participated in the "2023 Student Optical Design Competition" held by the International Society for Opto-Electronic Engineering (SPIE) in San Francisco, USA. Based on the research results of the optical design of AR glasses in cooperation between Beijing University of Science and Technology and ASUS Computer, 7 teams from the United States, France, etc. Stand out to win the championship and get a prize of 3,000 US dollars.

The 3-day SPIE AR|VR|MR conference at the SPIE Photonics West 2023 focuses on hardware development focusing on augmented reality, virtual reality and mixed reality, especially optics and photonics Research breakthroughs in this area.

Among them, in the "2023 Student Optical Design Competition", only one group from Beijing University of Science and Technology participated in Taiwan, and the other six participants were mostly doctoral students from top universities in the United States and France.

Qiu Bohan, a sophomore student from the Department of Optoelectronic Engineering at Beijing University of Science and Technology, gave a report. He pointed out that the weight, appearance, and image quality of AR glasses are the key factors that affect the user experience, and the diffractive waveguide display is to achieve lightweight, glasses-like appearance, The main technology for bright and uniform images, but there are few related design researches in the academic circle, and most of them focus on the material process and local optical structure. Therefore, the design process can only be developed from scratch by analyzing the published patents and articles in the industry.

Zheng Yujie, the instructor and associate professor of the Department of Optoelectronic Engineering of Beijing University of Science and Technology, further stated that the newly developed optical software of the team can meet the needs of optical designers, connect the automatic process from layout design to optical optimization, and achieve a diffraction waveguide with a large viewing angle of 60 degrees Design and present the optical tracing results of 4 degrees of freedom in an innovative way.

The team also stylized the layout design of the most complicated diffraction grating in the process of diffraction waveguide AR glasses. Through the interactive platform that can be operated by mobile phones, designers can input different design requirements on the visual interface and quickly obtain space. The layout of the medium grating will help AR glasses to expand market applications.
