[A tracker for ophthalmology].

Abstract:

:Real-time tracking of eye movements offers a solution to various problems in ophthalmology. Different types of image analysis and processing techniques is discussed and an advanced pattern recognition eye-tracking system has been developed; it can track a retinal target (in real time) under conditions typical for ophthalmologic examination and therapy. The sensor is a modified low-light video fundus camera. An example illustrates how a retinal target is automatically found again when it has been "lost".

  • [Suggestions for the design of a modern anomaloscope].

    abstract::Three variants of a new anomaloscope principle are described. This principle is distinguished by the fact that for generation of the mixed color and the reference color three interference filters with narrow band widths are used instead of an expensive dispersion prism. In the first variant the brightness of the mixed...
