Abstract

A system for classifying the various major types of blood cells is provided wherein blood cells are passed before a laser beam. The redirected light energy passing through the cell is applied to a detector array which provides a voltage spectrum representative of the spatial relationships of the object. This voltage spectrum is compared rapidly with different spectra representative of different blood cell classes. Whenever a best fit is detected by the comparing means, a count is scored in one of the cell classes. The same means is applicable to the analysis of other cell types such as cancer and exfoliated cells.
