摘要： A light source that projects a fixation mark into the eve and an image sensor that receives light that has been reflected, diffracted or scattered from the cornea, lens and retina of the eve. A digital camera that captures HDR images of the eve predominantly only with activated fixing illumination. A control unit is designed to detect reflections, as well as diffracted and scattered light of the fixing mark of eve structures in the images transferred from the image sensor and to optimize, evaluate and display the captured HDR images of the eye on a display unit. The invention is provided for different ophthalmological devices, but, in principle, it can be applied to other technical fields in which additional information of the object to be imaged is generated and correspondingly evaluated via the capturing of HDR images.
