Metalenz, a Boston-based provider of metasurface optics, has teamed with Chinese 3D sensing system supplier Dilusense to provide facial recognition for smart locks and payment kiosks, according to a press release.

The smart locks are designed for residential and commercial building access solutions while the payment kiosks will be used by retailers and in vending machines across China.

Facial authentication solutions use traditional cameras to recognize a user's face, then take an additional 3D infrared image to authenticate the user against pre-registered biometric credentials.

Using structured light, the 3D sensing system creates a point cloud made up of more than 30,000 individual dots and then measures pattern distortion to compute facial contours unique to each individual. The optical sensor in this system, Metalenz's Orion meta-optic dot projector, delivers dot-contrast, pattern precision and diffraction efficiency to increase the security of the system.

The meta-optics are custom designed by Metalenz and mass produced by UMC in its 12-inch wafer fab in Singapore as part of Metalenz's direct-to-OEM supply chain.
