Commercial camera sector gains hyperspectral imaging sensor technology

February 05, 2014 // By Graham Prophet
Belgian nanoelectronics research centre Imec is forming strategic partnerships to expand the ecosystem around its hyperspectral image sensor technology – that is, sensing specific optical bands both within and outside the visible spectrum - to enable its commercialisation into machine vision, medical imaging, remote sensing and global security markets.

Imec’s technology is an optical-filter-on-chip sensor solution, that has been integrated by different commercial camera vendors including ADIMEC (The Netherlands), 3D-One (The Netherlands), Tattile (Italy), and BaySpec (USA).

Hyperspectral imaging is not new in the world of high-end remote sensing instruments such as satellites and airborne systems. By applying narrow-band spectral filters at pixel level using semiconductor thin-film processing, imec’s technology enables hyperspectral image sensor solutions with extreme compactness, low weight, high reliability and proven capabilities to be mass-produced at low cost in volume. Such sensor solution is extremely valuable for camera vendors to access new markets such as drone UAVs (unmanned aerial vehicles) for precision agriculture, food quality grading in machine vision or in-vivo imaging for classification of medical tissues, among others.
