The “Lark,” an innovative polarized holographic waveguide AR glasses developed entirely by the research team at Southeast University’s School of Electronic Science and Engineering, made its debut recently.

During an interview on October 23, Professor Zhang Yuning, the head of the Information Display and Visualization Research Institute at Southeast University, shared, “Our goal is to present information in a more accessible way, achieving a ‘big picture from small devices.’ Traditional AR glasses often rely on surface relief grating technology, but our glasses utilize a polarized holographic grating, which significantly enhances light energy utilization and reduces manufacturing costs. This offers users a clearer, more efficient, and intelligent immersive AR experience.”

Weighing in at just 45 grams, the “Lark” is ultra-lightweight and designed for extended use, with features such as music playback, real-time translation, and precise navigation.

According to Professor Zhang, the “Lark” is a remarkable blend of original innovation from academia and advanced manufacturing capabilities. It represents an effective exploration between the academic and industrial sectors in nurturing and developing new productivity. The glasses received considerable attention during the 25th China International Optoelectronic Expo held in September 2024.

Jiang Xuehua, Party Secretary of the School of Electronic Science and Engineering, added, “Transforming scientific achievements into practical applications is a top priority for our school and the college. The focus on information display and imaging combines ‘tradition and innovation.’ The establishment of the Information Display and Visualization Research Institute serves as a testing ground for our scientific innovation and deep industry-academia collaboration. We aim to use this model to drive thorough cooperation through high-value technology output and efficient transformation of scientific achievements.”
