In this paper we are presenting the prototype of laser measuring system -- namely laser liner -- for Computer Numerical Control (CNC} machine tools and for Coordinate Measuring Machines (CMM). The laser liner is an innovatory arrangement of one frequency interferometer. The two-mode HeNe laser is used as a source of radiation whereas the surface stabilized ferroelectric liquid crystal cell (SSFLCC) for stabilization of the laser frequency. Small dimensions of the arrangements facilitate mounting of the interferometer on machine tools. Worked out advanced correction procedure of length of light wave compensates in real time the influence of parameters of atmosphere on the length of laser radiation. Another possible thing is compensation of thermal expansion of a material.
