Title
(EN) HIGH DISPERSION DIFFRACTION GRATING INCLUDING MULTIPLE HOLOGRAPHIC OPTICAL ELEMENTS
(FR) RÉSEAU DE DIFFRACTION À DISPERSION ÉLEVÉE INCLUANT DE MULTIPLES ÉLEMENTS OPTIQUES HOLOGRAPHIQUES
Abstract
(EN)
A multi-element diffraction grating is disclosed. The multi-element diffraction grating may be configured to diffract incident radiation with high dispersion using at least two holographic optical elements. The multi-element diffraction grating may include a first volume phase grating that is one of the holographic optical elements. The multi-element diffraction grating may also include at least one additional volume phase grating that is the second holographic optical element. The first volume phase grating and each of the additional volume phase gratings may be positioned relative to each other such that the radiation propagates through and is diffracted by the first volume phase grating and each of the additional volume phase gratings.

La présente invention concerne un réseau de diffraction multiélément. Le réseau de diffraction multiélément peut être configuré afin de diffracter un rayonnement incident avec une dispersion élevée en utilisant au moins deux éléments optiques holographiques. Le réseau de diffraction multiélément peut inclure un premier réseau de phase tridimensionnel qui est l'un des éléments optiques holographiques. Le réseau de diffraction multiélément peut également inclure au moins un réseau de phase tridimensionnel supplémentaire qui est le second élément optique holographique. Le premier réseau de phase tridimensionnel et chacun des réseaux de phase tridimensionnels supplémentaires peuvent être positionnés les uns par rapport aux autres de telle manière à ce que le rayonnement s'y propage et soit diffracté par le premier réseau de phase tridimensionnel et chacun des réseaux de phase tridimensionnels supplémentaires.
