ALLISON JOHNSON & RICHARD BUTLER, DPREVIEW:
Panasonic has been developing organic sensors for a while now and has just announced a new breakthrough: an organic CMOS chip that can capture visible and near-infrared (NIR) light simultaneously without sacrificing resolution.
There are sensors available now that can image both near-infrared and visible light, but they sacrifice one out of every four pixels to NIR capture. As a result, resolution of the final image suffers. Panasonic's new chip makes use of two organic layers: the top layer is sensitive to visible light and the bottom layer is sensitive to near-infrared light. By changing the voltage applied to the layers, it's possible to choose whether the lower layer is active or not. This means it can switch between visible and visible+NIR imaging frame by frame, which is useful in machine vision applications where subjects may be moving quickly.
