IMAGING AND ANALYZING PARAMETERS OF SMALL MOVING OBJECTS SUCH AS CELLS

摘要

Light from an object such as a cell moving through an imaging system is collected and dispersed so that it is imaged onto a plurality of separate detectors (321-325). The light is spectrally dispersed by a plurality of spaced-apart dichroic reflectors (301-304), each detector (321-325) receiving light from a different one of the dichroic reflectors (301-304). Each dichroic filter (301-304) reflects light of a different predefined color, passing light of other colors. The output signal from each detector (321-325) is indicative of a different characteristic of the object. In one configuration, each detector (321-325) is provided with a separate imaging lens (311-315). In another configuration, the detectors (321-325) are spaced at varying distances from the corresponding dichroic reflectors (301-304), so that separate imaging lenses are not required.
