Abstract:
An Ophthalmological apparatus comprising,an observation unit; an illuminating unit, from which an illumination beam emission is emittable in order to observe the eye, said illumination beam emission having a planar geometrical cross-sectional dimension and a two-dimensional intensity distribution; and a spatial light modulator having spatial optical properties, but no mechanical adjustment means, the spatial optical properties of said spatial light modulator are alterable and again reversible in order to confer said planar geometric cross-sectional dimension to a predetermined geometric cross-sectional dimension or said two-dimensional intensity distribution to a predeterminable two-dimensional intensity distribution in the form of an image information, on the beam emission incident upon the spatial light modulator, wherein a second beam emission differs from the illumination beam emission, the optical properties of the spatial light modulator are alterable by irradiation with said second beam emission, so that the image information generated with the spatial light modulator has raster-free image subareas.
