Lensless 3D Camera: How a Tiny Diffuser Sees Depth in One Shot
Imagine making a 3D picture without any lens — just a tiny piece of plastic in front of a sensor.
This simple idea turns light into a unique speckle pattern, and from that pattern a computer rebuilds depth.
The camera is lensless, small and cheap, yet it can capture a full scene in a single exposure called single-shot 3D.
One small plastic scatterer, a diffuser, makes every point in space leave its own fingerprint on the sensor.
Then software reads those fingerprints and fills a 3D map of the scene, sometimes recovering as many as 100 million points from a single 1.
3 megapixel photo.
Resolution can change with what you’re looking at, that’s normal so the team explains how to think about detail in such pictures.
It feels like magic, but it’s just clever light tricks and smart math.
You could build a compact 3D camera, or imagine new ways to scan rooms, plants or objects fast — and with very little gear.
