Abstract

When the illumination wavelength is comparable to the object size, one is in the Mie scattering regime. In this regime geometrical optics breaks down because of diffraction effects, and image data must be interpreted on the basis electromagnetic wave theory. Mie scattering problems are difficult to solve because the full vector form of Maxwell's equations must be solved subject to the appropriate boundary conditions, without the benefit of the short wavelength approximation. In this paper we present the essentials of Mie scattering theory, introduce algorithms for computing Mie scattering, and show how Mie scattering concepts can be used to image fast-moving microparticles by visible light.
