Paper Abstract

Particle sizing based on the phase Doppler technique is investigated for spheres having sizes of several light wavelengths by using a laser interferometer(a laser Doppler velocimeter) that has the receiving optics composed of paired optical fibers. The phase dependence on the particle size is calculated by means of multipole expansion of electro-magnetic fields and the calculated results are compared with those obtained from geometrical optics. Experiments using silicon resin particles have been conducted on the basis of oscillatory part of the phase curve.
