Abstract

We present the first application of a two-core photonic crystal fibre for fringe projection for use as a Doppler difference velocimeter. The two-core fibre projects a series of fringes when both cores are simultaneously illuminated with 633 nm light. Light scattered from moving particles is coupled into a separate multi-mode collection fibre and detected using a silicon detector and amplifier. The scattered signal is processed in the frequency domain to obtain the particle velocity component perpendicular to the fringes. © 2003 Published by Elsevier B.V.
