"Unlike conventional image sensors the chip has no pixel readout clock but signals the detected changes instantaneously. This information is signalled as so-called “events” that contain the information of the responding pixels x-y addresses (address-event) in the imager array and the associated timestamp via a synchronous timed addressevent-representation (TAER) interface. The sensor can produce two types of events for each pixel: “On”-events for a relative increase in light intensity and “Off”-events for a relative decrease (see diagram)."
AIT also makes a 360deg 3D scanner with its DVS sensor:
Thanks to TL for the links!
Fraunhofer? Or is there still someone else working in 0.35?

This sensor chip was presented 11 years ago(!)

On the AIT booth at Vision show they had a demo with the linescan DVS camera to inspect the dimond particles on a saw wire. Looked like a useful application. To me it seems that DVS is still looking for the right applications... Does anybody know if DVS cameras are already in broader use somewhere - and if yes, in what areas?
