XR Active Calibration (AA)

challenge

Break through the assembly bottleneck of AR optical machines and whole machines, and lead the era of high-precision mass production

In the field of AR glasses manufacturing that pursues the ultimate immersive experience, the active calibration (AA) of optical machine modules is the core link to achieve clear, comfortable and dizzy-free visual effects, and is also a key challenge for mass production implementation. Traditional calibration methods are often unable to meet the following complex needs:

◆ Multi-component precision coupling challenge: LCoS optical machines require accurate alignment between the imaging module, lighting module and screen, and the calibration solution for lighting modules has been missing for a long time; the three-color MicroLED optical machines face the problem of combined light offset of RGB chips, and require submicron-level accuracy to ensure that the color is pure and the picture coincides with.

◆ Complex optical aberration correction: Astigmatism brought by optical waveguides will significantly reduce edge imaging clarity and affect user experience.

◆ Binocular coordination and parallax elimination: The entire AR glasses machine needs to accurately synchronize the binocular eye machine to control the viewing angle difference to a very small range (such as ±0.5°), otherwise it is very easy to cause dizziness from the user.

◆ Balance between accuracy and efficiency: High-precision calibration often means inefficiency and is difficult to meet the requirements of UPH for large-scale mass production (such as 60 units/hour or higher). 

◆ High complexity of process integration: The calibration process requires seamless connection of subsequent processes such as dispensing, curing, focusing, and glue shrinkage compensation, and the process is complex.
