Abstract

Design and fabrication of an integrated backscatter fiber optic probe is described in this paper. A short section of a gradient index optical fiber is fusion spliced to two separate monomode optical fibers; the two fibers are mounted into a stainless steel face plate. One fiber is used to transmit either a focussed or collimated laser beam to the scattering region. The second fiber collects and guides the laser light scattered at a predefined scattering angle to a photomultiplier. Subsequent photon correlation and analysis yields size information of the scattering species.
