Apple has been awarded a new patent for the next-generation Face ID technology. This patent utilizes metasurface optical elements (MOE) to replace traditional diffractive optical elements (DOE), effectively integrating beam splitting and collimation functions. This groundbreaking innovation not only slashes the module size and production costs but also elevates assembly precision to new heights. Additionally, the MOE technology fine-tunes the optical axis tilt angle, resulting in enhanced 3D mapping accuracy. The device further boasts a controller that enables the alternating activation of spot and flood illumination, seamlessly adapting to diverse scenario demands.
