Title:
IMAGING UNIT
Document Type and Number:
WIPO Patent Application WO/2014/140189
Kind Code:
A3
Abstract:
An imager contains an image sensor with laterally varying spectral response. The imager is scanned over a scene or object to form a spectral image. The spectral responses are repeated at different positions in the field of view so as to reduce the effect of scene nonidealities, such as angle dependence or temporal variation, on the spectral image data. A part of the image sensor may be used for conventional two- dimensional imaging. This part of the image sensor may be used to estimate the scene geometry and scan movement, enabling further improvement in the spectral integrity.
