Link: This experimental camera can focus on everything at once

Researchers at Carnegie Mellon University have developed a lens technology that focuses on multiple points simultaneously, drastically improving image clarity. This "spatially-varying autofocus" system uses a mix of advanced optics and computational techniques.

The technology integrates a Lohmann lens and a spatial light modulator to achieve sharpness at various depths. It employs two methods of autofocus: Contrast-Detection and Phase-Detection.

Traditional camera lenses can only focus on one distance at a time, often resulting in parts of the image being out of focus. The revolutionary system from CMU can focus across multiple focal planes without losing detail.

This breakthrough could potentially transform the way cameras are used across various fields, from virtual reality to autonomous driving. It promises to deliver a level of detail and depth previously unattainable with standard photography equipment.

The new lens technology is still in the experimental stage and is not yet available for commercial use. It might be some time before it appears on the market, if at all.

CMU researchers believe this new focusing mechanism could also enhance other technologies like microscopes, VR headsets, and vehicles, by ensuring clearer and more precise visuals. #
