Patent DE 10 2008 050 540

Arrangement for processing an analogue sensor output signal (Sa) of at least one optical sensor (1), for position determination, in the form of a position determination unit (1a) combining the optical sensor and components for determining the position, with at least one optical sensor and an interpolator module (2) connected to the optical sensor and arranged directly behind the sensor and combining the components for determining the position from the sensor signal, characterised in that the interpolator module contains an AD converter unit (3) for generating a digitised sensor signal (SD) and a programmable signal processing unit (4) for calculating an interpolated position value (P), that the interpolator module contains an AD converter unit (3) for generating a digitised sensor signal (SD) and a programmable signal processing unit (4) for calculating an interpolated position value (P), wherein the signal processing unit (4) is designed as a programmable hardware, wherein the programmable hardware has a hardware-implemented program code for a tracking unit (8) for carrying out an interpolating position determination, wherein the hardware-implemented program code is designed for a tracking algorithm for a control loop support distance compensation calculation.
