At the recent SPIE 2026 event held in the United States, beyond product exhibitions, Appotronics Corporation Limited was invited to present two advanced technical sessions on AR, attracting significant attention from experts and industry professionals in the fields of optics, optoelectronics, and AR/VR from around the world.
Appotronics Corporation Limited delivered its technical presentations at SPIE 2026.
SPIE Photonics West is the world's largest and most influential comprehensive international event in the fields of photonics, lasers, biomedical optics, and optical engineering. It is not a single exhibition but a "week of events" comprising multiple top-tier academic conferences and a large-scale industry exhibition. The first technical presentation delivered by Appotronics was titled "System-level optimized high-efficiency compact RGB laser LCoS AR light engine." The presentation highlighted that by leveraging the inherent advantages of laser diodes over LEDs—such as polarization, low étendue, and narrow bandwidth—the research achieved high optical efficiency, a compact structure, and DCI-P3 color gamut. A core breakthrough lies in the integration of an efficient laser speckle suppression module and the adoption of a front-illuminated, non-polarizing beam splitter architecture, further reducing the size of the optical engine. This research focuses on the "laser + LCoS" technological pathway, aiming to overcome challenges in speckle elimination and thermal management, thereby providing a practical system framework for high-performance AR display devices. The second report, titled "High-resolution Lissajous scanning light engine with wide field of view for AR glasses," addressed the demands of AR glasses for lightweight design, low power consumption, and large field-of-view high-definition display by proposing an innovative laser scanning imaging solution. Compared to Micro LED and raster scanning, laser combined with Lissajous scanning galvanometers shows greater potential in system compactness and energy efficiency; however, traditional Lissajous scanning faces resolution limitations at large fields of view. Through a specially designed MEMS galvanometer, Appotronics transformed the Lissajous scanning pattern into one resembling raster scanning, significantly simplifying subsequent image processing algorithms. Combined with a multi-emitter laser, this technology aims to achieve a field of view exceeding 60 degrees with full HD-level resolution, potentially overcoming the bottleneck where Laser Beam Scanning (LBS) technology struggles to balance large field of view and high definition in AR glasses, thereby advancing its practical application and industrialization. It is worth noting that prior to Appotronics' presentation, the Meta team delivered a report titled "On-chip laser beam scanner based on SiN PIC integrated with PZT MEMS cantilever for AR," also expressing optimism for laser beam scanning technology. Overall, the technical presentations at SPIE demonstrated Appotronics Corporation Limited's continuous innovation and technological accumulation in the AR field, and they are expected to provide important insights and viable pathways for the development of AR display technology.
