Multispectral filter for image sensor, improved image-sensing device for a multispectral imager and multispectral imager incorporating this filter

摘要

The filter (88) has a prismatic plate (85) provided with an internal surface (86) and an external surface (87). The internal and external surfaces are inclined with respect to each other with a prism angle (beta). Different spectral bands are equally arranged on the internal surface or the external surface. The bands are spaced with respect to one another with a predetermined distance. An independent claim is also included for a multispectral imager comprising an image detection device.
