ABSTRACT:
A system and method permits for the separation of auto-fluorescence from a signal by applying a single probe to a sample, exciting the sample with a single wavelength light source, thereby emitting a light a distance from the light source. The emitted light is split, and the split light is collected into two or more distinct channels. A first channel of the distinct channels is positioned closer to the light source than a second distinct channel of the distinct channels, and the second channel is closer to the emission frequency of the single probe than is the first channel. The light collected in the first channel and the light collected in the second channel are investigated, and an output signal is generated based upon the investigation.
