AN APPARATUS AND A METHOD FOR IMAGING

摘要

An apparatus (100) and a method is provided. An apparatus (100), comprising: at least one color separation diffraction grating (10) configured to direct different spectral components (51, 52, 53) of incident light (40) in different directions; one or more further diffraction gratings (20) configured to at least partially compensate for dispersion in one or more of the different spectral components of light (51, 52, 53); and one or more image sensors (30) configured to detect the one or more dispersion compensated spectral components of light (61, 62, 63).
