Abstract
Light from an object such as a cell moving through an imaging system is collected and dispersed so that it can be imaged onto a detector. The light can be emitted from a luminous object or can be light from a light source that has been scattered or not absorbed by the object or can include a light emission by one or more probes within or on the object. Multiple objects passing through the imaging system can be imaged, producing both scatter images and dispersed images at different locations on one or more detectors. In one embodiment, the detector is divided into a plurality of zones so that each of a plurality of different images are spectrally dispersed onto a different zone of the detector.
