Abstract

The invention discloses a signal carrier device, system and equipment for displacement measurement. The signal carrier device comprises an information storage medium and a displacement measurement code channel formed on the information storage medium, the displacement measurement code channel comprises a relative displacement measurement code channel, and the relative displacement measurement codechannel comprises protrusions and pits which are continuously, alternately and evenly arranged.

Description

technical field [0001] The present invention relates to the technical field of displacement measurement, and more specifically, to a signal carrier device for displacement measurement, a displacement measurement system, and a machine device. Background technique [0002] Displacement sensors can be divided into gratings, magnetic gratings, capacitive gratings, ball grids, inductive synchros and time gratings according to the applied technical principles. Among them, gratings are the most widely used in displacement measurement, especially mid-to-high-end grating sensors. This is because the sampling frequency, resolution, precision and performance of the grating sensor are unmatched by other types of displacement sensors. [0003] The installation accuracy of the light source, mask grating, moving grating scale and photoelectric sensor included in the mid-to-high-end grating sensor is very high, so that the mid-to-high-end grating sensor can achieve high-precision measureme...
