Introduction to R&D and Production Enterprises ——

        Chinama Optoelectronics Technology is a professional and experienced team led by a senior engineer of the Chinese National Army who has been engaged in the research and development of holographic diffraction optics for 30 years. Chinama Optoelectronics has a strong R&D process in the international holographic light field information recording materials and derived holographic diffraction core optical technology. At present, we are the first to independently develop holographic waveguides, 85-degree ultra-large field of view retinal projection HOE, ultra-large area holographic waveguides and other products, with clear imaging, and are in an international leading position.
       Holographic optical waveguides based on holographic light field information recording materials are the mainstream optical solutions for global AR optics today, the next generation of computing interaction platforms, the core key to the next thirty years of civilization, and the basic core components of AR. In the field of AR, they are optical components with a higher strategic level than chips, and are widely used in industrial and consumer AR smart glasses, single-soldier combat helmets, traffic police helmet displays, armored vehicles and flight 360-degree surround aiming helmets, vehicle-mounted and airborne HUDs and other fields.

      With the progress of automobile intelligence, consumers have put forward more and more stringent requirements for driving safety and driving experience. Head-up display system (HUD), a fighter jet technology introduced to automobiles in the 1980s, will have great potential. Early HUDs had problems such as poor display effects and high costs, and were less popular. However, with the development and promotion of large manufacturers in various countries, the current low-cost solutions and display effects have been greatly improved. In particular, the introduction of augmented reality (AR) technology, integrating advanced driving assistance systems such as ADAS and ACC, and projecting navigation and driving information in real time to the front of the vehicle and combining it with physical objects can obtain a better sense of technology and driving experience. AR-HUD is now in mass production, which will bring about the vigorous development of the HUD industry again.

      Based on years of volume grating research and development technology, Chinama Optoelectronics Technology Group has mastered the “manufacturing process of multi-grating waveguide surface integration” and built a multi-grating waveguide surface integration platform or equipment to achieve high-quality manufacturing of multiple similar gratings on the waveguide surface. At the same time, 2022 Achieve batch manufacturing every year. Next, Chinama Optoelectronics Technology Group analyzed the competitive advantages of holographic optical waveguide optical solutions, as well as the target markets of holographic optical waveguides – AR glasses, cockpit AR-HUD and other streamlined optical paths, ultimately achieving a significant reduction in system volume and significantly improved performance. application module.

      The HUD head-up display system is one of the important components that integrates the environmental sensors of the driver assistance system as well as GPS data, map data and driving dynamics data to establish a close network connection. Integrating AR (augmented reality) technology into HUD is the currently popular AR-HUD. Compared with traditional W-HUD, AR-HUD has a longer virtual image distance VID (＞7.5m, or even infinity), a larger field of view FOV (＞10°*3°), and a larger virtual image size (tens of inches). The virtual image can cover multiple lanes and integrate with the traffic environment ahead.

      However, after years of technological accumulation, W-HUD has achieved batch shipments, and the mass production rate continues to increase. Mainstream manufacturers such as Mercedes-Benz S-Class, Volkswagen, Audi, Hongqi, Great Wall, and GAC have also begun to try AR-HUD with better display effects. As one of the core configurations of automotive intelligence, the cool effect of AR-HUD has won unanimous praise from the market. In the future, it will become a standard configuration for automakers in the field of smart cars, and the market is ushering in rapid development.

      The existing AR HUD projection methods are, on the one hand, the DLP technology solution represented by Mercedes-Benz, and on the other hand, the TFT technology used by Volkswagen, Hongqi, Great Wall, etc.Although AR-HUD has been widely used in high-end vehicles in recent years, there are still difficulties such as sunlight backflow, overall size, and cost that require further in-depth research and better solutions. Therefore, in addition to optimizing optical design and materials, mainstream manufacturers such as LCOS and Chinama Optoelectronics Technology Group still invest a lot of energy every year to carry out in-depth research and development.

      Since the AR-HUD in-vehicle head-up display system was launched in the domestic and foreign markets in 2022, it has been widely used and well received by well-known automobile companies (such as BAIC Group, TCL Huaxing Electronics, etc.). In 2024, it has increased huge R&D investments with major corporate groups to further build and launch the next-generation panoramic HUD system for implementation and mass production.

      Chinama Optoelectronics Technology has inherited more than 20 years of technology and is a research and development-oriented group enterprise. From laser holographic micro-nano imprinted thin film optical materials to high-end laser holographic micro-nano optoelectronic system components, Chinama Optoelectronics Technology is one of the few group enterprises in China that has mastered the preparation of laser holographic diffraction gratings from the early stage of lithography to the subsequent full process. The holographic diffraction optical elements and holographic optical waveguides developed and manufactured can be widely used in aerospace, flight aiming helmets, infantry aiming helmets, rapid aiming devices for individual weapons, benchmark measurement, medical equipment, spectrometers, smart electronic products, 3D printers, 3D scanners, network and information security technology (hardware and software) and systems, Internet of Things, electronic special equipment and instruments, advanced perception and reconnaissance detection, blockchain technology, virtual augmented reality technology, simulation technology, space-time benchmark technology and equipment and other fields. In particular, the AR augmented reality core hardware developed and manufactured by the group has broad market application scenarios – holographic waveguide gratings, AR retinal projection lens gratings, etc. The products have a small shrinkage ratio, high imaging resolution, stable state, and superior comprehensive performance. Some technical indicators even exceed the US Eotech-holographic technology.
