Abstract: An image generating apparatus is provided, which has a plurality of image generating optical paths and means for simultaneously deflecting a received plurality of light beams of primary illumination light having coherence properties. The received light beams are assigned to the respective optical paths. The means for deflecting simultaneously optically couples each of the received light beams into a respective assigned optical path and irradiates intermediate faces of illumination units of each respective optical path with the respective assigned light beam. The means for deflecting is configured so that, during the process of irradiating, each of the light beams subsequently in time irradiates different portions of the respective assigned intermediate faces.

Abstract: An imaging unit including a first spectral splitting and illumination part and a second spectral splitting and recombination part. Within the first spectral splitting part received white light is split up into a first spectral component and a second spectral component. In the second spectral splitting part the second spectral component is split up into a third spectral component and a fourth spectral component. Additionally, first, second, and third partial images of an image to be generated are produced with respect to the first, third, and fourth spectral components of the white light. The first, second, and third partial images are recombined to obtain a recombined or reproduced image. The second spectral and polarization selective splitting and recombination part includes a dichloric beam splitting device and first and second polarization selective or polarizing beam splitting devices.
