Rx and Tx Advantages

On the world facing side (Rx) of camera systems, Metalenz meta-optics offer significant imaging advantages when compared to conventional lens stacks including; 4 to 1 lens reduction, 2x more light, and 40% noise reduction.
On the front facing side (Tx) of camera systems, Metalenz meta-optics offer significant illumination advantages when compared to conventional DOE modules including; Higher contrast ratio, wider field of illumination, and superior part to part repeatability.

Structured Light

Mobile device companies use structured light (SL) high resolution 3D sensing technology to enhance security by unlocking the phone when the owner’s face is recognized. SL is also used to enhance the functionality of the selfie camera. SL systems project a pattern of infrared light onto the user’s face and measure distortion in the return signal to obtain a 3D map of the face and confirm the user’s identity. Unfortunately, the face identification system does not always recognize the user’s face, especially if the user is in sunlight or is further from the phone. Meta-optics will play a key role in making face identification more robust.
SL projectors use light from VCSEL arrays to create a complex pattern of dots on its target. Typically, these dot patterns are projected by diffractive optics, however, it may require several lenses in addition to the diffractive. Meta-optics, with as few as a single element, can project dot patterns with superior performance to a diffractive optic. The advantages include higher efficiency, wider field of view, more dots, and better contrast. Metalenz technical benefits result in a face identification that works better, particularly when the person is further away from the phone or in sunlight.

Our metasurface technology is now in the market in STMicroelectronics FlightSense™ ToF products for consumer electronics.

Benefits of Meta-optics

01
When compared to meta-optics (MOEs), diffractive optics (DOEs) exhibit substantially higher stray light and lower imaging performance at low f/# and across temperature.
02
4x improvement in signal to noise in 3D imaging systems.
03
Complete control over the intensity, phase, and polarization of light.
04
Multifunctional optics replace an entire set of refractive lenses, resulting in lower cost of integration and assembly.
05
Metalenses are fabricated with a single semiconductor layer for high yield, cost effective mass production.
06
Reflow compatible, extreme temperature stability.
