New lensless camera creates detailed 3-D images without scanning

The lensless DiffuserCam consists of a diffuser placed in front of a sensor (bumpson the diffuser are exaggerated for illustration). The system turns a 3-D scene into a 2-D image on the sensor.

For the first time, engineers at Caltech have created a stable ring of plasma in open air—essentially capturing lightning in a bottle, but without the bottle. Matter can exist in four distinct phases: solid, liquid, gas, and plasma. Plasmas are made of charged particles—ions and electrons—and occur naturally on Earth as lightning, in the weather…
