3D printing has changed the way people approach hardware design, but most printers share a basic limitation: they essentially build objects layer by layer, generally from the bottom up. This new ...

Its detector converts light from the LED into a voltage that a National Instruments data-acquisition card can digitize. That lets the tester measure light intensity. An optical fiber attached to the ...

A fresh approach to stereolithographic printing has increased both the speed and reliability of this means of fabricating three-dimensional objects. Stereolithographic printing builds each layer of a ...

Researchers have developed a new optical microprobe able to control brain electrical activity by projecting light on wide volumes or selected portions of the central nervous system in an very ...
