Paper Abstract

Experimental results of the usefulness of the fiber-optic Sagnac interferometer for a measurement of angular position as motion uniformity of slow-speed rotating objects are presented. The system contains GS-13P/SR device with modified signal processing unit. The results of an investigation of this system, and their application for rotation angle and uniformity motion of object in inertial space are shown. A new slow-speed platforms generate constant angular motion (M19-03 stand made by COBRABiD Optica) and harmonic variable motion (STW-1 stand made by AFIT) have been used as forces source. The Fourier and wavelets analyses have been used as mathematical description of GS-13P/SR application for technical diagnostic of slow- speed platforms.
