Patent ID: 7977625

Claim:
Arrangement for the generation of optical section images, consisting of an illumination unit, an optical arrangement for the imaging of the sample onto at least one spatially resolving detector, focussing means as well as a signal processing unit, for the implementation of a method for optical reproduction with depth discrimination, wherein the illumination unit, without any moving mechanical elements, creates each with only two different illumination distributions in respective on the sample, the illumination distributions have a periodicity in at least one spatial direction, the sample plane in which the illumination distribution is created is conjugated with respect to the plane of the corresponding spatially resolving detector, the light distributions within the sample resulting from the interaction with the illumination light are registered sequentially or simultaneously on said one or more spatially resolving detectors and fed to the signal processing unit in real-time for the calculation and generating of an optical section image wherein furthermore two illumination distributions are simultaneously projected and detected, where the light used for both projections is different with respect to polarization and/or spectral composition, where these different properties of the illumination light lead to different properties of the light distributions simultaneously emitted from the sample and these properties of the light emitted from the sample are used to separate the illumination patterns on the detection side.
