Unlike traditional lenses, metalenses are flat and made of silicon with intricate patterns etched into them. These patterns allow precise control of light, enabling new possibilities in imaging and sensing.
Metalenses can see through glare, haze, and even black ice, and can also be used for identity verification, detecting artificial faces, and recognizing cancerous skin growths.
The manufacturing process for metalenses is similar to that of computer chips, making them smaller, cheaper, and easier to mass produce. As metamaterials become more widely available, they are set to revolutionize mobile devices, cars, and medical technology, transforming how we observe and interact with the world.

When taking physics in undergrad and thinking about how to make space telescopes that can image exoplanets. The idea of a lens that can capture all the information contained in the photons in a nanometer size region space would allow this but until now I had no idea they actually had something that can do this. This would enable the mass production of a fleet of telescopes that can collectively image incredibly small and far away things.

[@Skinflaps_Meatslapper]

There's already talk of using the sun as a gravitational lens to magnify a point far behind it in the same way we get gravitational lensing in deep space images. If one could someday locally manipulate gravity, one could focus the light to a small point made of meta-lenses and extrapolate a ridiculous amount of information that we'd never be able to see without physically being there.

[@homo-sapiens-dubium]

sadly, you'd still need X amount of photons, which would require a _huge_ collection surface for this kind of project. I doubt that inferometry based optics would be more efficient in "collecting" light than a plain mirror? An interesting idea for this project is to use the sun as a gravitational lens. There is an interesting paper from JPL on this, presented by this "friendly neighborhood astronomer Prof. of astronomy youtuber", forgot his name though...

[@SeanOHanlon]

Astronomy was the first application I thought of as well. The metalenses could conceivably detect virtually everything across the entire light spectrum without the need for sub zero cooling.

I've been dreaming about metalenses for years. This is the holy grail of the lenses and it will be a revolution in smartphone cameras.

[@Vaeldarg]

Magic Leap's CEO often talked about their waveguide being an "optical processor" (might be misremembering the exact term used). So a much more impressive use than the camera of a smartphone, would be for optical computing. When using photons, there's a MUCH larger processing bandwidth achieved due to the different wavelengths can use independent of each other. The different pieces have been slowly being developed for a while now, and hopefully can soon be brought together.

I, and many others, were making these routinely in our labs in the late 1980s. There are many published papers on the subject. My first Ph.D. student went on to found a company that sold these commercially in the 1990s. If Metalens has any advance over old technology, it's not apparent from the video.

[@xstrxd]

Lately I've been wondering if the sort of tech used in phased array radars and to steer wifi/cellular beams is applicable to visible light. What i'm wondering is this mostly based on the same principle?

[@atmel9077]

This video and the company's website present it as an obscure new technology... from what I understand, this is a holographic lens, holograms were invented in the 60s and have to be made on photographic plates, the real innovation here is to make the hologram using photolithography. Another possible innovation is to control both the amplitude and phase of the interference pattern, making this an in-between of holograms and spatial light modulators, and would allow to remove the conjugate image. The big problem is that such a lens can only work with a single wavelength of light and can only be used with laser illumination. Could be used for machine vision applications, but it's certainly not going to replace camera lenses anytime soon. The video illustrates the patterns of the lens with tiny colored shapes... nope, the pattern is probably concentric circles, what is called a fresnel zone plate.

[@atmel9077]

@@xstrxd Yes, it's called a hologram, and it's sort of an optical phased array. The "beam-steering" properties of holograms allows them to record images of 3-dimensional objects. Holograms were also used in the 60s and 70s to reconstruct images taken by radar satellites

Optics only get so complicated because we need more optics to correct for the faults in the original optics, but even the correcting optics themselves need correcting. You just can't win. Meta lenses don't need any of that and that makes them simpler and much better.

They got a correction piece of glass for the correction piece of glass for the correction piece of glass and so on haha That near perfect no focus breathing is unreal.

[@2dozen22s]

A telescope built with these would be fantastic, since CMOS image sensors and meta lenses are both made via photolithographic processes you could feasibly order multiple wafers and make them a bunch of self contained units. Each one a mini telescope. Then package them in into a VLBI orbital observatory. Also I'm not sure about the maximum angle, but since silicon is invisible to some IR, you could make a Sensor + support-silicon + metalense stacked die for very small cameras?

[@Vermiliontea]

Light doesn't scale. When it comes to cameras and lenses (or optical mirrors) there is no substitute for size. This video is exactly correct when it emphasizes that it offers extracting more information _inside_ the image. That is also all it offers. But we don't know yet what that will lead to. Better identification and diagnosing probably, that sounds very plausible. Military AI that is better at discerning the hiding russian soldiers it will plink with mini grenades, maybe. Having AI machinery to 'see' more will maybe be the biggest application.

[@kepler_22b83]

My guess is that the polarization detection will offload a very big portion of an AI's work when it tries to see 3d... Computer vision would become more reliable, and if it can see more than a human, the possibilities for it are endless.

Meta-materials will change our world, and how we look at it. This specific tech, can also be used as a magnifier to see both the very small, and the very far. I Love how this can be used to 'see' much broader wavelength as well. Light bending meta-materials for cloaking has been tested for at least a decade. Meta-matrials can be used for most, if not all wavelengths, enhancing things like antennas and sensors. In a way, we have been using such materials for decades already. DLP, lab on a chip, the microscopic sensor that detects acceleration in everything from your car to your cellphone. As you could see, this was made in a fab. Only our imagination limit what kind of 'machines' we can shrink down on to a microchip...

Metamaterial optical lenses aren't new.

See the Wikipedia entry: Superlens. The first microscope Superlens using a metamaterial increased the resolving power of a light microscope from 200 nanometers to 100 mn in 1981. Putting together the mathematics, computer power, and fabrication facilities to design and build Metalenz's metamaterial lenses will change many facets of optics. The prediction of size and mass creates a whole new kind of camera.

Before subscribing to a channel I typically view a bunch of their videos. Not this time, you got me.

this would be perfect for headsets with the metaverse. the branding is even there already.

I like the unknown part of the impact this technology will have. Smartphone is a platform for individuals, it is amazing how it will continue to develop with new technologies.

Can these meta lense also let us see sounds and let us see (almost) every scent?

correction> refraction isn't about the material affecting the speed of light, it affects the angle of the light. aka refractive index

We demand polarised car windscreens, car lights, glasses etc.Thank you

That's what I was thinking. Unless I'm misunderstanding, it seemed like the claim was that polarizing light, even without the use of these micro-lenses, would make black ice visible to the human eye. If that is the case, it seems like (at least for people who live in climates where roads freeze over), one of the first things that should be done to a newly purchased vehicle, would be to have a polarizing film adhered to the windshield.

@@Inertia888 100% agree, polarised film will reduce sun glare and car light glare etc.

I know that it is already a work of art, but it would be awesome to see meta materials be used to make gallery art. 0:10
