A system for determining the absolute position of a first object with respect to a second object includes a scalar element attached to the first object and a measuring device attached to the second object. The scalar element comprises a series of coded regions. The coded region represents a number designating a position along an axis of the scalar element. The measuring device includes a two-dimensional optical sensor array configured to capture an image of a portion of the scalar element. The system also includes a processor configured to receive the image and determine an absolute position of the first object with respect to the second object based on at least one coded region of the series of coded regions.

Absolute position detection

The invention relates to a dosing device for dispensing and/or receiving a dosed amount of a liquid, comprising a piston device being disposed in a housing and a device for determining the stroke of the piston and/or the position of the piston, wherein the device for determining the stroke of the piston and/or the position of the piston features at least one scalar element and at least one measuring device, wherein the scalar element is fixedly disposed at the housing of the piston device and the measuring device is directly or indirectly connected to the piston and can be moved together with the piston, or wherein the scalar element is disposed at the piston so as to be movable with the piston and the measuring device is fixedly disposed at the housing, and wherein the scalar element is designed as an absolutely coded scale.
