Abstract :
The cell analyzer, an automated apparatus for biological studies of live cells, is discussed. The major enhancement of the cell signal is performed optically using a microscope in bright field microscopy mode. By appropriate selection and arrangement of the optics, a characteristic cell signal that can be easily distinguished from most debris signals is obtained. Several focusing algorithms are discussed, and the results of some recognition experiments are presented
