| contents | A robust and compact magneto-optical rotary encoder for the characterisation of robotic rotary joints is demonstrated. The system employs magnetic field-induced optical attenuation in a double-pass configuration using rotating nonuniform magnets around an optical circulator operating in reflection. The encoder tracks continuous 360° rotation with rotation sweep rates from ν = 135 °/s to ν = 370 °/s, and an angular resolution of Δθ = 0.3°. This offers a low-cost and reliable alternative to conventional robot rotation encoders while maintaining competitive performance. |
