Abstract: In the paper, a misalignment and field magnification tolerance analysis for the coupling efficiency of fiber optic rotary joint was presented. The analysis consisted of output position deviations from different wavelengths, dove prism manufacturing errors, light tilt and decenter errors. It helped manufacturers easily defined component specifications and assembly tolerances for fiber optic rotary joint. The 2 mm spot size was best suited for current assembly tolerances. The 2 mm beam diameter of coupling efficiency was over 80% in the tilt error ±10 arcmin and decenter error ±250 μm. In the future, we could create a FORJ system according to the simulation parameters. The practice experiment data would compare to our simulation results that used to prove our simulation results.
