Abstract
An appliance for recording an image of an ocular fundus includes an irradiating device with a radiation source and optical components for generating an illumination strip. A scanning device is set up to cause a scanning movement of the illumination strip for the purpose of scanning the ocular fundus. An optoelectronic sensor senses detection light issuing from the ocular fundus. The optoelectronic sensor has a plurality of sensor rows and is set up such that charges contained in one sensor row are each shifted, with a time delay, into a further sensor row. A control means is connected to the scanning device and/or to the optoelectronic sensor and is set up to control the scanning movement and/or the time delay.

A device for imaging an ocular fundus, comprising:
- an irradiating device with a radiation source and optical components that generate an illumination strip;
- a scanning device that is configured to cause a scanning movement of the illumination strip such that the illumination strip is scanned over the ocular fundus;
- an optoelectronic sensor that records detection light originating from the ocular fundus;
- wherein the optoelectronic sensor includes a plurality of sensor rows and is configured such that charges contained in one sensor row are each shifted, with a time delay, into a further sensor row;
- and
- a controller which is operably coupled with the scanning device, the optoelectronic sensor or both the scanning device and the optoelectronic sensor and configured to control the scanning movement, the time delay or both the scanning movement and the time delay.
A method for imaging an ocular fundus, comprising:
- generating an illumination strip;
- causing a scanning movement of the illumination strip such that the illumination strip is scanned over the ocular fundus;
- and
- recording detection light originating from the ocular fundus with an optoelectronic sensor which has a plurality of sensor rows and shifts, with a time delay, charges contained in one sensor row into a further sensor row;
- wherein either the scanning movement, the time delay or both the scanning movement and the time delay are adjusted such that the time delay and the scanning movement are synchronized.
