High-quality photos can now be taken without a single lens, using only a flat sensor and a genetic algorithm to reconstruct the image.

The Takeaway
Lenses are the heaviest and most expensive part of any camera system, from microscopes to telescopes. This technology replaces the glass lens with a computational system that decodes the messy pattern of light hitting a sensor. By using physics-guided genetic programming, it can produce clear images of tiny biological cells or large objects. The system is much thinner and more durable than traditional optics. This allows for cameras that are as thin as a piece of tape but can still capture professional-grade detail.
From the abstract
Lensless optical imaging eliminates the need for refractive optics, enabling compact and low-cost cameras with a large field-of-view, supporting point-of-care diagnostics and industrial monitoring. Practical deployments, however, remain constrained by ill-posed image reconstruction pipelines that require multiple measurements, careful calibration or object-specific training, thus limiting robustness and scalability. In this work, we introduce a single-shot lensless imaging framework that reconst
