The development of optical instruments to infer the size of transparent or opaque particles from their scattering characteristics is currently an active research area. A number of techniques are being used based on either the Doppler signal visibility1–8, signal amplitude9–11, the spatial phase difference between Doppler signals12–15, or a combination of these parameters. Each one of these methods requires the experimentally measured parameters to be converted into particle size through theoretically computed relationships, using either Mie scattering theory, geometrical optics computations, or Fraunhofer diffraction theory.
