A line and a space are collectively referred to as the division interval. Signal period When scanning the grating, sinusoidal signals are generated, the period of which corresponds to a graduation interval. interpolation The sinusoidal measurement signals are subdivided n-fold depending on the required subdivision factor and converted into square-wave signals by an electronic circuit. Measuring step Smallest counting step that can be shown in the display device depending on the division interval and interpolation factor. Line count Number of division intervals per revolution (angle of rotation detection). Reference pulse Reference marks are used to clearly define the count value at a certain position on the measuring section. A signal peak (reference pulse) is generated at this position. A reference pulse is reproducibly output with one counting step when the reference mark is passed from both directions. Interfering signal Monitoring of the scanning signals. accuracy Decisive feature of a measuring device, which is indicated by accuracy classes (e.g. ± 5 µm / m). Abbe mistake Measurement deviation in the event of a lateral offset between the linear encoder and the working plane. Yaw angle, pitch angle, roll angle, displacement, distance Degrees of freedom when assembling the scanning unit.
