Abstract
A device for examining the eye fundus and photoreceptors includes an illumination beam path having optical beam forming and/or guiding components, at least one illumination unit for providing a continuous illumination and a flash illumination, and an observation and imaging beam path having optical beam forming and/or guiding components and a device for varying the magnification, including a beam splitter for splitting the observation and imaging beam path. A rotatable diffraction grating is disposed in a plane in the observation and imaging beam path that is conjugate to the object plane and the movement of the grating is synchronized with the illumination unit that serves as the flash illumination so that an image recording sensor records a rapid sequence of images of the eye fundus at different positions of the grating and said sequence is forwarded to an existing evaluation unit.
