  • Publication number: 20020005934
    Abstract: For purposes of examination, the human eye at a defined viewing point is oriented along a viewing axis. Using means associated with a first light source, stimuli are generated at selectable locations on the background of the viewing axis. Using a second light source, a homogeneous background light is generated around the viewing axis. The second light source has at least one LED. This LED can be actuated as required so that it generates a constant background light or a flickering background light. If at least two LEDs are used, the one LED can generate a colored background light by means of a fixed colored filter. No moving parts are necessary for the generation of a flickering background light, nor any means for the active cooling of the second light source.
