Optical measurement system

An optical measuring apparatus, comprising:

• a reference support on which are mounted a fixed headstock,
• a movable tailstock opposed to the fixed headstock,
• a mobile optical carriage movable in range from said headstock to said tailstock, said tailstock and said optical carnage being movable along a linear axis (x), a piece under measurement being maintained between said headstock and said tailstock in direction of said x axis, said optical carriage carrying a light source for directing a beam of light across said x axis to be interrupted by the said piece under measurement, said carriage further carrying an optical detector aligned with said light source and arranged to receive residual light of said beam of light that has not been interrupted by said piece under measurement,
• one or more rectilinear guides, fastened on the reference support, said optical carnage and said tailstock being slideably engaged on said one or more guides and being slideable along said x axis, whereas said fixed headstock is placed on a headstock carrier that is fastened on the reference support and hangs at least in part over said one or more guides, the headstock further including a fixed calibration body inside the back of said headstock earner, along the same axis of the piece under measurement, enabling measurement of the alignment and the slope of the detector;
• and
• a stationary casing enclosing said light source and said optical detector, the casing having two windows allowing the passage of said beam of light along the motion path of said optical carriage, said windows being hidden at least in part by two flexible tapes connected in two loops and driven in common with the carriage.
