摘要:
A display unit for binocular representation of a multicolor image including a control unit triggering an imaging element such that the imaging element generates in a temporal successive manner the image to be displayed for a first beam path and a second beam path as a first image and second image, respectively. The images are generated in a pre-distorted manner, opposite of the chromatic aberration of the respective beam path, such that the chromatic aberration generated in the respective beam path is compensated when the first and second image is displayed. The display unit includes a switching module which operates in temporal synchrony with the first and second image being generated, such that a user can see the first image only via the first beam path and the second image only via the second beam path.

摘要:
A system includes an optical system having two beam splitters (a dichroic beam splitter and a polarizing beam splitter), which are designed to provide three separate beam paths for observing an object. The dichroic beam splitter is designed to separate two beam paths depending on the wavelength of the light of the respective beam path. The polarizing beam splitter is designed such that two beam paths are separated depending on a direction of polarization of the light of the respective beam path. The measuring light is linearly polarized after having passed the polarizing beam splitter and may be influenced with respect to the state of polarization by a retarding plate. The returning measuring light incident on the polarizing beam splitter is linearly polarized and also polarized in such a direction that the returning measuring light is transported through the polarizing beam splitter towards the analyzing detector with a high efficiency.
