Large-Scaled Details Flatness Measurement Method

The paper represents large-scaled prismatic details flatness measurement method based on datum realized by laser source, PSD and electronic level. Principal of operation, software and the analysis of metrological and functional characteristics of the measuring system are described. The system is intended to be used for measurements and control of flatness deviations of the NICA's project yoke of twin aperture dipole magnets and quadrupole lenses of the Buster and Collider in the town of Dubna, Russia.
