Abstract[English]
The invention relates to a light modulation device (1) for a microscope (100) comprising a first active area (11) of a wavefront modulator (10,10a) and a second active area (12) of a wavefront modulator (10,10b), wherein the first active area (11) and the second active area (12) are configured to modulate a wavefront of a light beam (L) dependent on a polarization of the light beam (L), wherein the first active area (11) and the second active area (12) intersect a light path along which the light beam (L) propagates, wherein the light modulation device (1) comprises a first polarization switching element (20) configured to rotate the polarization of the light beam (L)between a first polarization direction (P1) and a second polarization direction (P2) upon receiving a switching signal (S) to selectively modulate the wavefront of the light beam (L) by the first active area (11) and/or the second active area (12). The invention further relates to a microscope (100) comprising the light modulation device (1) and a method for modulating a light beam (L) for microscopy.[French]
L'invention concerne un dispositif de modulation de lumière (1) pour un microscope (100) comprenant une première zone active (11) d'un modulateur de front d'onde (10,10a) et une seconde zone active (12) d'un modulateur de front d'onde (10,10b), la première zone active (11) et la seconde zone active (12) sont configurées pour moduler un front d'onde d'un faisceau lumineux (L) dépendant d'une polarisation du faisceau lumineux (L), la première zone active (11) et la seconde zone active (12) coupant un trajet de lumière le long duquel le faisceau lumineux (L) se propage, le dispositif de modulation de lumière (1) comprenant un premier élément de commutation de polarisation (20) configuré pour faire tourner la polarisation du faisceau lumineux (L) entre une première direction de polarisation (P1) et une seconde direction de polarisation (P2) lors de la réception d'un signal de commutation (S) pour moduler sélectivement le front d'onde du faisceau lumineux (L) par la première zone active (11) et/ou la seconde zone active (12). L'invention concerne en outre un microscope (100) comprenant le dispositif de modulation de lumière (1) et un procédé de modulation d'un faisceau lumineux (L) pour la microscopie.
