Optics and artificial intelligence have converged to create a new imaging system that could transform photography. By integrating AI-driven corrections with metalenses—flat, nanoscale lenses—researchers have overcome the long-standing challenges of miniaturizing lenses while maintaining image quality.

Metalenses, introduced in the 2010s, replace curved glass with nanoscale structures to control light. Their flat, lightweight design makes them ideal for compact devices, but they have struggled with chromatic aberrations and poor image quality in varied lighting. These limitations have kept them from replacing traditional multi-layered glass lenses.

Researchers have now paired metalenses with deep learning. This system uses a neural network—a type of AI that processes data like a human brain—to correct distortions in images captured by metalenses. The result is an end-to-end process that produces sharp, full-color images comparable to or better than traditional optics.

The team tested the system using 10-millimeter metalenses manufactured with scalable techniques for mass production. While the lenses excel at resolving fine details, they cannot fully correct distortions on their own. The neural network compensates for this, refining the raw image data to produce high-resolution results free of chromatic distortions.
