The invention relates to an optical system for generating a pattern which changes over time for a confocal microscope comprising a light source arrangement (1, 12a, 12b, 12c) from which light beams travel to an object (7) which reflects the light beams, a beam splitter (3) for allowing passage of the light beams proceeding from the light source arrangement (1, 12a, 12b, 12c) in the direction of the object (7) and for deflecting the light beams reflected by the object (7) in a focal plane in the direction of a detector (8) with a detector pattern for detecting an image of the object (7) and a lens arrangement (4a, 4b) between the beam splitter (3) and the object (7). In particular the light source arrangement (1, 12a, 12b, 12c) has at least one light source (1) and an arrangement (12a, 12b, 12c) which switches over the light beams emitted by the at least one light source (1) with respect to their direction of polarization for generating a changing projector pattern (2) without moving a mask with the projector (2) pattern. |
