Method and system for dispersion measurements

摘要

A method for determining a size or shape related parameter of an effective observation volume for an observation technique for particles undergoing at least partially stochastic motion in a dispersion is based on a time-series of observations. The method involves determining one or more time-dependent characteristics of the dispersion or its particles based on the time-series of observations, determining at least one stochastic motion-related parameter representative for the at least partially stochastic motion of at least one particle in the dispersion, and determining a size or shape related parameter of the effective observation volume by modeling of the at least partially stochastic motion of the particle movement in the dispersion, the modeling taking into account the at least one stochastic motion-related parameter and the determined one or more characteristics.

1. A method for determining a size or shape related parameter of an effective observation volume for an observation technique for particles undergoing at least partially stochastic motion in a dispersion, based on a time-series of observations, comprising:
detecting the particles of the dispersion in the effective observation volume to obtain a time-series of observations of the particles, determining one or more time-dependent characteristics of the dispersion or the particles, based on the obtained time-series of observations, determining at least one stochastic motion-related parameter representative for the at least partially stochastic motion of at least one particle in the dispersion, determining a size or shape related parameter of the effective observation volume by modeling of the at least partially stochastic motion of the particle movement in the dispersion, the modeling taking into account the at least one stochastic motion-related parameter and the determined one or more time-dependent characteristics, wherein the size or shape related parameter of the effective observation volume at least takes into account the distance from a nearest detectable particle to a most distant detectable particle in the effective observation volume, and determining a concentration of particles in the dispersion based on the size or shape related parameter of the effective observation volume and the one or more characteristics.
