Non-destructive determination of the refractive-index profile provides a valuable tool for assessment and quality control of optical-fibre preforms. The spatial-filtering technique allows data to be rapidly and conveniently acquired, and we have reported high-resolution profiling of both multimode and single-mode preforms by this method, together with comparative results obtained by other means. We report here an assessment of the factors influencing the accuracy and resolution of the technique and outline some of the improvements which have been made
