The usefulness of the Mathematica 3D-visualization and animation for investigation of fiber-optic loop interferometers in different engineering applications
work is presented. The Jones' matrix calculus has been used for description of fiber-optic elements of all interferometric
systems. Such uniform description gives a possibility to obtain analytical relations, which depend on fundamental system parameters.
Unfortunately, these relations are usually too complicated for physical interpretation. The possibility of their analysis
by the animated 3D graphics is also shown in the present paper.
