Abstract
A method for adjusting a detector () for determining a position of at least one object () within a range of measurement () is disclosed. The detector () comprises at least two longitudinal optical sensors () and at least one transfer device () for imaging the object () into an image plane. The transfer device () has a focal plane. The transfer device () is positioned in between the longitudinal optical sensors () and the object (). Each of the longitudinal optical sensors () has at least one sensor region (). Each of the longitudinal optical sensors () is designed to generate at least one longitudinal sensor signal in a manner dependent on an illumination of the respective sensor region () by at least one light beam () propagating from the object () to the detector (), wherein the longitudinal sensor signal, given the same total power of the illumination, is dependent on a beam cross-section of the light beam () in the sensor region (). The detector () further comprises at least one evaluation device (). The method comprises the following steps: (i) subsequently moving the object () longitudinally to at least two different calibration positions () having at least two different longitudinal coordinates within the range of measurement (); (ii) recording, for each of the calibration positions (), at least one first longitudinal sensor signal generated by a first longitudinal optical sensor () and at least one second longitudinal sensor signal generated by a second longitudinal optical sensor (); (iii) forming, for each of the calibration positions (), at least one calibration signal using the first and second longitudinal sensor signals; (iv) generating a calibration function using the calibration signals, the calibration function defining a relationship between the longitudinal coordinate of the object () and the first and second longitudinal sensor signals.
