The present invention relates to a method for determining a distribution of a parameter, e.g. cross-sectional area, of a particle population for identifying specific types of particles therein. A plurality of images of the particles are detected on a pixel array and a number of pixels in the form of a pixel count is determined for each of the plurality of images of particles. Weighting factors, e.g. a probability which relate values of the parameter to different pixel counts are used to determine the distribution for the parameter of the particle population. The method depends on the facts that the total population to be analyzed contains many particles and is uniformly distributed, over many frames, throughout the optical sampling volume, and that even when substantial uncertainty exists on the parameter value corresponding any individual image, the statistical information which is obtained from many images may be used to provide accurate distributions.
A method for determining a distribution of a parameter of a particle population comprising the steps of:
In a system for analyzing a parameter in a particle population in a fluid, wherein particles are substantially randomly distributed, and particles range in value from X1 to X10, in increments, values of X1, through X10 being different values, a method of determining a total number of particles within a sampled volume having a predetermined parameter value, comprising the steps of:
