1. Apparatus for analyzing particles suspended in a fluid medium, comprising:

  • an image detector for obtaining at least one still image of a plurality of particles suspended in a fluid medium;

    an image analyzing unit for measuring from said at least one still image at least two dimensional characteristics per particle for each of said plurality of particles appearing in said at least one still image and for determining an occurrence characteristic of particles which is related to the particles having a matching set of measured dimensional characteristics; and

    a display unit for presenting a three dimensional representation of said measured dimensional characteristics and said occurrence characteristics of all said plurality of particles appearing in said image and providing information about said plurality of particles in a manner which permits a viewer of said three dimensional representation to determine a size and shape distribution of said plurality of particles appearing in said at least one still image.
