PRECISION DISPLACEMENT MEASURING SYSTEM AND METHOD FOR INDUSTRIAL MACHINES

摘要

A precision measuring system (1) for industrial machines is disclosed, particularly for numerically-controlled machine tools, particularly for measuring the linear displacement transduction of an object (40) comprising at least one optical system (20) equipped with at least one CCD-type optical sensor (10) adapted to acquire images of the object (40) in time; and acquiring, processing and computing means (30) of video signals (80) generated by the CCD-type optical sensor (10) adapted to determine measure signals (90) representing an amount of a displacement of the object (40). A measuring process using the system (1) is further disclosed.
