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.
