    In the era of Internet of Thing (IoT), large FOV AR see-through display devices such as head-up-display (HUD) and head-mounted-display (HMD) make it possible for the human to communicate with the world in a totally different way from before. In addition to the connected devices, the new communication method highly depends on the information layer generated by display network and will create immerging demand on large FOV AR display. However, the large FOV AR see-through display using traditional cascaded concave mirror is bulky and heavy with poor display performance due to low contrast and low brightness. The long design cycle and high manufacture difficulty of traditional macro optics also limit the development of AR display. Therefore, the solution for light weight, high contrast, and high brightness large FOV AR display is in need. In this project, the Unified Field System Design Methodology will be adopted to optimize and accelerate the optics system design process, and advanced diffractive and holographic micro-optics will be applied to replace traditional macro optics to enhance display performance and reduce optics weight. To achieve the design target, we will develop ASTRI patented platform technologies including real-time Noise depressed CGH Algorithm, multi-layer Diffractive Optical Element (DOE), and hybrid functions HOE w/ notch filter & lens. These technologies can be widely applied in both AR display and VR display in various industries, such as automotive, aviation, education, household products, navigation, and media. The estimated global market for AR and VR display would be more than 15 billion in 2021 and would reach 20 billion by the year 2023. This project is committed to promoting the development of AR display in Hong Kong and Asia Pacific, and to helping Hong Kong become the R&D center with leading edge technologies on optics design. This project has attracted some Tier-one companies in the world, such as Delphi, Huawei, to cooperate with ASTRI and will benefit local industry, bolster industrial capabilities, and accelerate the market development.
