| titleOfInvention | Endoscopic and/or exoscopic imaging device for spectral imaging, and method for the operation thereof |
| abstract | The invention relates to an endoscopic and/or exoscopic imaging device (10) for spectral, in particular multispectral and/or hyperspectral, imaging for an endoscope (12), microscope (13) and/or an exoscope (14), comprising at least one shaft (16) and comprising at least one imaging channel (18) situated at least in part in the shaft (16), which imaging channel comprises at least one first imaging branch (20) that has at least one first spectrally selective beam splitter (22) that spectrally selectively splits an optical image (24) of an original spectral range (28, 32, 44, 48, 64, 68) into at least one first partial spectral image (26) of a first spectral range (28) and at least one further first partial spectral image (30) of a further first spectral range (32), wherein the first spectral range (28) is different from the further first spectral range (32), and the first imaging branch (20) comprises a first image sensor (34), at least for capturing the first partial spectral image (26), and the first imaging branch (20) comprises at least one first relay lens (36) for relaying the further first partial image (30). According to the invention, the imaging channel (18) comprises at least one second imaging branch (38) that has at least one second spectrally selective beam splitter (40) that spectrally selectively splits the further first partial image (30) of the further first spectral range (32) into at least a second partial spectral image (42) of a second spectral range (44) and at least one further second partial spectral image (46) of a further second spectral range (48), wherein the second spectral range (44) is different from the further second spectral range (48), and the second imaging branch (38) comprises at least one second image sensor (50) at least for capturing the second partial spectral image (42), and the second imaging branch (38) comprises at least one second relay lens (52) for relaying the further second partial image (46), wherein the first relay lens (36) of the first imaging branch (20) and the second relay lens (52) of the second imaging branch (38) are arranged one behind the other so that an image plane (54) of the first relay lens (36) is identical to the object plane (56) of the second relay lens (52). |
