Abstract
The invention relates to an image sensor comprising: •an optical system () for receiving an optical signal; •a Bayer matrix () located on the image focal plane of the optical system (), the Bayer matrix () comprising: a reference optical filter (B) configured to eliminate or attenuate, in the received optical signal, a first band of wavelengths and to allow through, in the received optical signal, a second band length of wavelengths, and also eight optical filters adjacent to the reference optical filter (B); •a phase mask () arranged on a pupil () of the optical system () and configured to selectively project at least 98% of the energy of the optical signal carried in the first band of wavelengths and 98% of the energy of the optical signal carried in the second band of wavelengths on the reference optical filter (B) and on at least one adjacent optical filter, which is configured to allow through, in the received optical signal, the first band of wavelengths.
