Abstract
The invention is an illumination unit for point illumination of a medium where at least one light emitter is arranged to illuminate at least one illumination face via a first lens arrangement and a microshutter arrangement. The lens arrangement has at least one microlens arranged with respect to each microshutter so that light emitted from the light emitter is focused on or in the vicinity of the optical axis of the light channel of the individual microshutters. The fed coherent light from the light emitters is modulated by the microshutters onto the illumination face.
