Patent ID: 8388135

Claim:
An ophthalmological biometric or image-producing system, comprising: a measurement arrangement with an illumination unit that illuminates the eye with at least one measurement beam; a signal detection unit that captures light scattered or reflected back from the eye; a central control unit including an output unit and a central control unit-activated pattern generating unit which includes an optical scan unit, a control unit that controls the optical scan unit's deflection of at least one measurement beam with regard to the eye structures; a position sensor that measures realized deflections of the optical scan unit; wherein the control unit, the optical scan unit, and the position sensor either form a control loop or do not form a control loop; wherein the position sensor, in addition to connection within the control loop if the control loop is present, comprises a connection to a unit of the measurement arrangement that optimizes measurement value logging or a connection to the central control unit that corrects the biometric measurements or image data.
