ABSTRACT:
The invention describes a method and computer program product for the evaluation of data recorded by measuring instruments, which is particularly applicable to the precise localization of non-reflecting marks on a reflecting medium by means of a light-sensitive receiver and can be especially applied in precision positioning devices. The method comprises a first step in which data are recorded from a sensor on a measuring instrument with a minimized or extinguished measured signal and which is stored as a dark curve, a second step in which data of a normalized measured signal are recorded and stored as a reference curve, and a third step in which data for the current measurement are recorded and stored as a characteristic curve; the characteristic curve is then purged of errors caused by the measuring instrument by comparison against the dark curve or reference curve and normalized and the characteristic curve thus treated is stored as the target curve, and finally the target curve is evaluated for various values of the measured signal. The computer program product can be loaded directly into the internal memory of a computer and comprises software code sections, with which the above described method may be carried out when the product is running on a computer.
