A stereoscopic imaging system in the form of a microscope for generating pairs of stereoscopic half-images comprising a taking system having: - a single electronic image sensor that has an electronic shutter for setting a charge integration time of the image sensor; - an objective for generating an image of an object on the image sensor, wherein the objective has a single imaging optical path having a central optical axis; - a double aperture diaphragm that is arranged in the imaging optical path and that has two mutually spaced apart apertures (26a, 26b) that are offset from the optical axis and that divide the imaging optical path into respective part optical paths (28a, 28b), wherein the part optical paths (28a, 28b) differ with respect to their viewing angle of the object; - a rotating shutter assembly that is associated with the double aperture diaphragm, that uncovers one of the two apertures (26a, 26b) alternately in time for a predefined time period in accordance with a speed of rotation and that closes the other one of the two apertures (26a, 26b) at least during this time period in order to release one of the two part optical paths (28a, 28b) and to interrupt the other one of the two part optical paths (28a, 28b) alternately in time; and - a synchronization and control device that is adapted to synchronize the charge integration time set by the electronic shutter of the image sensor and the speed of rotation of the rotating shutter assembly with one another such that the image sensor detects a respective stereoscopic half-image on the basis of the released part optical path (28a, 28b) during the named time period, characterized in that the imaging system is adapted to select one of at least two predefined spectral ranges that is taken into account by the image sensor for detecting a respective pair of stereoscopic half-images, with the imaging system further being adapted to select the spectral range alternately in time and to associate the pairs of stereoscopic half-images to a corresponding image group in dependence on the selected spectral range such that only those half-images are associated with each image group that correspond to the same selected spectral range. - a single electronic image sensor that has an electronic shutter for setting a charge integration time of the image sensor; - an objective for generating an image of an object on the image sensor, wherein the objective has a single imaging optical path having a central optical axis; - a double aperture diaphragm that is arranged in the imaging optical path and that has two mutually spaced apart apertures (26a, 26b) that are offset from the optical axis and that divide the imaging optical path into respective part optical paths (28a, 28b), wherein the part optical paths (28a, 28b) differ with respect to their viewing angle of the object; - a rotating shutter assembly that is associated with the double aperture diaphragm, that uncovers one of the two apertures (26a, 26b) alternately in time for a predefined time period in accordance with a speed of rotation and that closes the other one of the two apertures (26a, 26b) at least during this time period in order to release one of the two part optical paths (28a, 28b) and to interrupt the other one of the two part optical paths (28a, 28b) alternately in time; and - a synchronization and control device that is adapted to synchronize the charge integration time set by the electronic shutter of the image sensor and the speed of rotation of the rotating shutter assembly with one another such that the image sensor detects a respective stereoscopic half-image on the basis of the released part optical path (28a, 28b) during the named time period,
