最近的500亿美元的交易，为其AR眼镜购买牛津的Waveoptics的关键供应商，有很大的影响。供应商看到手机市场高原，增强现实系统是下一个显示技术。像手机一样，欧洲公司正在开发技术中发挥着关键作用。
“我喜欢相信我们在2005年与MEMS加速度计相同的变化水平，现在我们看到了手机正在下降的拐点，我们相信AR可以是下一个大事，”马可艾格里奇说MEMS执行器业务部门在STMicroelectronics中充电，来自MEMS侧和驾驶员侧，包括拉萨和Qanta联盟。
“我们希望瞄准手机的尽头，”他说。
ST is focussing on laser beam scanning using mircomachined (MEMS) mirrors, which is in the market with several different technologies. For example, Microsoft’s Hololens is using laser scanning, and so is North which was acquired by Google. ST also has an automotive joint design win for 2024/25 with Leddartech for automotive lidar using the technology.
ST拥有一系列MEMS技术，从电容和静电到压电，给公司一系列不同的方法。对于第一激光器AR系统。该公司从红色，绿色和蓝色激光二极管的梁静电控制开始，这些设备现在正在采样，但是对于MEMS镜子的压电控制器，在米兰和新加坡的ST'S 8IN Fab上建造。
”基于“增大化现实”技术的压电我们认为是正确的技术,”he said. “Piezo material is a big area of research, to improve the force and efficiency and this gives us a scalability roadmap to improve the power consumption. It’s a capacitive load and we include energy recovery to reduce the power consumption.
The company had already started working on the piezo technology and acquired bTendoin 2012 for its Scanning Laser Projection engine. A key capability is the energy recovery as the piezo material relaxes, which can reduce the overall power, critical for wearable designs.
“At the beginning of 2020 we decided to have a parallel path [for a standard product] alongside key selected customers with customised solutions to start addressing the problem of an optical engine for the AR market. We are not targeting the fully immersive XR market but the AR smart glasses for all day wearing and we started working with partners to match all the ingredients.”
This led to the LASAR Alliance, bringing together various companies for a complete AR system. This combines the laser diodes and MEMS mirror for the optical engine and the optical waveguide to provide the display it the glasses. The same technologies can be used in high volume automotive designs.
“随着Lasar联盟，我们打算与供应链中的主要公司合作，刺激全系统。他说，联盟现已纳入IEEE标准，以便我们可以向最大的公司列表，即希望加入，“他说。
“Piezo is at the core of the mirrors and we are working together with the A*Star laboratory in Singapore and ULVAC to build an R&D centre for piezoelectric materials in our ST fab. This uses the same equipment as the production line to deliver a prototype that is ready to move into production.”
“然后我们需要有人为客户制造完整的系统，这是非常重要的Quanta。”
目的是整天可穿戴的AR眼镜，重量小于60克，功耗为500mW。“我们可以实现今年的户外应用亮度1000次，与需要变暗的镜片的500个显示器相比，30至50度的视野（FOV）就足够了，”他说。
“最后有一个功耗的权衡。您构建波导的方式是您丢失视野的地方。增加视野意味着能量将能量转移到镜片的组合中，因此限制是在波导的顶层上具有良好的视野具有良好的颜色均匀性，并且我们正在使用波导制造商来获得60〜6070deg。今天沃洛尔有55度视场，但军方要求超过85度。“
他说，带有压电MEMS镜的激光二极管在整个系统上具有功率优势。
“We are able to illuminate on a per pixel basis so what we found from the Lasar Alliance was we don’t need a full frame buffer in the video processor so can use one or two lines, and we don’t need a backlight or illuminated substrate.
“The way we do the laser driver is customised, we integrate look ahead logic to switch pixels off when there are consecutive black pixels. With a key customer we find what comes out of the application processor so we can switch off more pixels so we focus on the fast rise and fall time,” he said.
“在MEMS侧面，我们开发了能量恢复，在我们重复使用上一个周期的能量 - 我们已经建立了一个带有集成电容的驱动器，在芯片中的压电中，我们在同步上有专利以产生下一个电压。“
“我们在德国举办欧司朗，为激光二极管，从光学发动机形成的光束必须成形为与波导的耦合。这是一个关键要素，我们与关键合作伙伴合作，并为此提供了高效的设计，我们知道我们需要为下一代做些什么。
The waveguide is essentially the physical lens of the glasses. In the North design there was a holographic reflective film on the lens of the glasses to project an image into the retina, but this needed a precise fitting. In contrast, diffractive etching on the glass of the lens takes the beams from the optical engine and reflects it into the side of the lens of the glasses using total internal reflection with a much larger ‘eye box’, or viewing area, of 10mm compared to 1mm.
静电光学引擎是北北代眼镜960 x 600p使用的批量生产，这是对关键客户的采样。他说，下一代将是40度的视野，瞄准50度。
The design being developed within the LASAR Alliance is different, with a diffractive waveguide. “We selected a diffractive waveguide to give a 10mm eye box which retina display or holographics waveguides can’t do,” he said. “The eye box is important to have one size fits all.”
This is supplied by Dispelix in Finland, and will be combined with the next generation optical engine from ST for prototype glasses that weigh 58g.
“我们正在建立一代名为Star1的新一代，从现在的几个月内使用65DEG FOV和1280 x 720P分辨率和0.7CC，使用帧缓冲和能量回收，从第一代中将功耗降低50％。”
STAR0的功耗为1220mW，为10％的白色显示器为742MW，取决于视频的复杂性，而Star1为781MW，持续为312MW，持续10％。
“到2023/24我们将在致动中有50％的改进，并将减少芯片大小30％，减少50％，或90％，给出了FOV或1080p的决议，”Angelici说。
