Paper Abstract

An improved ratiometric wavelength measurement system incorporating two fibre comb filters is presented, which performs both rough and fine wavelength measurements simultaneously. The resolution of the system is significantly improved, compared to a single edge filter system, to better than 5 pm while maintaining the potential for high measurement speed and wide measurable wavelength range.
