Imec Scientific Report 2012 has an extended section on image sensors. There are BSI, eCCD, 3D stereo developments and more. A hyperspectral imagers part shows the sensor structure and spectral response:
(a) Concept of tiled layout (filter heights exaggerated for illustration); (b) a packaged tile-based hyperspectral sensor; (c) Table with key specifications of tile based spectral imager. |
Spectral response of few selected filter bands from the wedge-based spectral sensor. |
