Abstract
Scattered light patterns produced by spherical transparent particles of a wide range of diameters (1–100 μm) and for a useful range of forward scattering angles (0–20°) are calculated by using both Lorenz-Mie theory and geometrical optics theory. A detailed comparison of the results leads to a definitive assessment of the accuracy of geometrical optics theory in the forward direction. Emphasis is put on simultaneous sizing and velocimetry of particles using pedestal calibration methods.This publication has 10 references indexed in Scilit:
