Abrégé
(EN)

An interlaced diffraction grating system and process are disclosed. The interlaced grating system includes an optical dispersive grating with alternating bands of unique grating densities wherein the number of unique grating densities is greater than or equal to two. The optical dispersive grating may be reflective or transmissive, and it may be fabricated by mechanical ruling, holography, or reactive ion etching of a binary mask. An interlaced grating allows additional utility for both point spectroscopic detection as well as hyperspectral imaging.
