Lensless cameras could turn windows into sensors, even pointed the ‘wrong’ way

Researchers believe lensless cameras may pave the way for tiny future cameras, but the latest academic experiment with an lens-free camera uses something that already exists as a “lens” instead: a window.

Researchers at the University of Utah recently shared a lensless camera that works by using a window — and is actually pointed the “wrong” way.

The lensless camera is a computational camera designed to decipher data and reconstruct the image, rather than a traditional camera that captures the scene as is.

Instead of focusing the light with physical glass, a computer is trained to decipher the unfocused light.

Associate professor and research head Rajesh Menon calls it designing cameras for machines, instead of for humans.

And while the University of Utah team didn’t use a lens, they did use glass.
