<pre>The artificial eye from Harvard has surpassed the natural

Scientists from Harvard reported on the solution to the compatibility problem of the technology “metalins” and artificial muscles, which are needed to control the artificial eye. Their prototype has a thickness of only 30 microns, but can in real time simultaneously focus, correct aberrations, astigmatism and other types of blurring, which are problematic to compensate for by traditional optical systems. And he, in theory, is universal.

Adaptive metalinses are structures that can fragmentally deform at the nanoscale, change their structure to compensate for optical aberrations. But for this it is necessary to attach very precisely to them a series of efforts, for which it is necessary to think up how to control artificial muscles. Only one description of the parameters of the structure of the metal lens with a diameter of 1 cm and a thickness of 30 microns occupies several terabytes, and when the device is scaled, its complexity increases incredibly.

In Harvard, they are proud of the fact that they developed algorithms for minimizing these calculations, simplified the control systems for metalinses to a level where the technology could be implemented in integrated circuits. Plus, they solved the problem of fixing the muscles to the lens – they picked up a polymer with suitable parameters for scattering the light passing through it. Now both the metal and the control systems are concentrated in one plane – this is a kind of ready-made module for integration into other optical systems.

In the theory of metal with artificial muscles can find application in photo and video equipment, telescopes, electronic eyes of robots, implants, microscopes and virtual reality glasses. In practice, the technology is still very far from the commercial embodiment – the scientists only combined two key elements, but the performance of this tandem still needs to be worked on.
