  • Abstract
    The optical contrast of the refracted near-field measurement method for fibre refractive-index profiles has been improved by a factor of about five by using numerical apertures adapted to the coupler to be measured. A spatial resolution of 0.3 mu m was achieved by deconvolving with the effective scanning near field.
