Measurements of light scattering by a glass fiber at an angle of 0 deg were successfully made at a wavelength of 0.5145 micrometers. Data were obtained as a function of fiber radii from 1 micrometer to 35 micrometers and are in excellent agreement with theory. This new measurement technique is based on the fanning of coherent light beam in a photorefractive BaTiO3 crystal. The use of fanning is a variant on the beam coupling technique originally proposed and since it is much more robust approach, it is significant additional accomplishment under this grant.
