Abstract
An apparatus and method for determining motility and other characteristics of cells in a fluid medium employing both the scattering and transmission of light through that medium and the absorption of shorter wavelength light by the cell with subsequent emission of fluorescent light. Both forms of light are imaged on an image detection apparatus, the output of which is analyzed as a function of time to produce the information concerning the characteristics of the cell.
