Abstract:
1. A system for capturing multi source excitations from a single location on a flow channel comprising: a light subsystem that emits light onto a single location on a flow channel, wherein the light subsystem includes a first excitation source that emits light at a first wavelength and a second excitation source that emits light at a second wavelength that is different from the first wavelength, wherein the light subsystem modulates between the following excitation source operating modes: a detector subsystem to that detects light emitted from the single location on the flow channel and generates a composite signal; and a processor coupled to the detector subsystem and adapted to separate the composite signal into composite mode signals each corresponding to a respective excitation source operating mode, wherein the processor is adapted to separate a composite mode signal into component mode signals corresponding to at least two overlapping emission spectra of fluorophores.
