Abstract
A method for measuring displacements based on a logometric method using a branched fiber-optic collector is analyzed. An analytical model of an optical-electronic probe of small axial displacements has been developed, and significant factors influencing the character of the calibration characteristic have been determined. The light-energy analysis of the optical scheme of the measuring optoelectronic probe is carried out, and the optical loss along the optical path length is estimated.
