Exclusive: Metalenz Has Figured Out a Way to Make Face ID Invisible

We're each too acquainted with the notch—the unsightly cut-in that graced galore smartphones for years, similar the iPhone X oregon the LG G7.

The notch has mostly been replaced connected today’s smartphones by floating punch-hole cameras that instrumentality up little abstraction and look a small much futuristic, though notches are inactive prevalent connected immoderate laptops, similar Apple’s MacBooks.

On the iPhone, Apple calls its floating pill-shaped camera strategy the Dynamic Island, which debuted connected the iPhone 14. The iPhone inactive has the largest camera cutout today, owed to its Face ID biometric authentication system. (Barring Google Pixel phones, the immense bulk of Android phones don't connection a unafraid look authentication equivalent, truthful they don't request a bulky camera cutout.) This land could get overmuch smaller, however, acknowledgment to caller under-display camera exertion announced astatine Display Week 2026 from Metalenz, a optics startup from Boston.

A Primer connected Metasurfaces

Metalenz’s optical metasurfaces exertion is simply a flat-lens strategy that uses a fraction of the abstraction of accepted multi-lens elements successful astir smartphones. You tin work much astir it successful our archetypal sum of the institution here, but successful short, alternatively of refracting airy done aggregate integrative oregon solid lens elements—which improves representation clarity, corrects aberrations, and brings much airy to the camera sensor—metasurfaces usage a azygous lens with nanostructures to crook airy rays toward the sensors.

Metalenz says much than 300 cardinal of its metasurfaces are already utilized successful user devices today, replacing bulky accepted optics successful time-of-flight sensors that seizure extent accusation and assistance with a camera's autofocus.

The institution besides pioneered a method to usage these metasurfaces to seizure polarization data. When airy hits an entity with circumstantial worldly properties, it creates a unsocial polarization signature. Light reflecting disconnected achromatic crystal has a antithetic polarization signature from airy reflecting disconnected the road. Using instrumentality learning algorithms, this enables a strategy that tin rapidly place achromatic crystal connected the roadworthy and alert the driver.

That's wherefore the institution developed Polar ID, a facial authentication level to rival Apple's Face ID. With polarization data, its sensors tin separate a existent look from idiosyncratic wearing an eerily close 3D disguise of the aforesaid person, due to the fact that the polarization accusation from airy bouncing disconnected a human's tegument is unsocial compared to airy bouncing disconnected the silicone of the mask. Yes, it's adjacent much unafraid than Google's look unlock strategy connected Pixels, which tin beryllium spoofed with a high-quality 3D mask.
