Abstract
An ophthalmological biometric or image-producing system and method for detection and analysis of measurement data including a measurement arrangement with an illumination unit for illuminating the eye with at least one measurement beam, a signal detection unit for the detection of the light portions scattered or reflected back from the eye, a central control unit with an output unit, and a pattern generating unit which includes an optical scan unit, a control unit as well as a position sensor for measuring the realized deflections of the optical scan unit, whereby control unit, optical scan unit and position sensor can form a control circuit. Thereby, the position sensor, except for the connection within the possible control circuit, includes a connection to a unit of the measurement arrangement for optimizing measurement value logging or to the central control unit for correcting the biometric measurements or tomograms.
