Title (EN) METHOD AND APPARATUS FOR OPTICAL IMAGING VIA SPECTRAL ENCODING
(FR) PROCEDE ET DISPOSITIF D'IMAGERIE OPTIQUE PAR CODAGE SPECTRAL
Abstract:
(EN) Method, apparatus and arrangement according an exemplary embodiment of the present invention can be provided for generating an image of at least one portion of an anatomical structure. For example, the portion can have an area greater than about 1 mm2, and the image can have a resolution a transverse resolution that is below about lOμm. For example, light can be scanned over such portion so as to generate first information which is related to the portion, where the light may be provided through a diffraction arrangement to generate a spectrally dispersed line. Method, apparatus and arrangement according to a further exemplary embodiment of the present invention can be provided for positioning a radiation or optical beam within an anatomical structure based on signals generated by scanning a portion of the structure using the same or a different beam.
(FR) Dans un mode de réalisation préféré, l'invention concerne un procédé, un appareil et une installation pour générer une image d'une partie au moins d'une structure anatomique. Par exemple, cette partie peut avoir une surface supérieur à environ 1 mm2 et l'image peut avoir une résolution latérale inférieure à environ 10 µm. Par exemple, la lumière peut balayer cette partie de manière à générer une première information relative à ladite partie, la lumière étant fournie par une installation de diffraction pour générer une ligne de dispersion spectrale. Dans un autre mode de réalisation, l'invention concerne un procédé, un appareil et une installation pour positionner un faisceau optique ou de radiation sur une structure anatomique sur la base de signaux générés par balayage d'une partie de la structure au moyen du même faisceau ou d'un autre faisceau.
