Abstract
An apparatus and method employing a plurality of light emitting devices which each can get light through a respective optical fiber toward a respective sample of a plurality of samples in a time-staggered manner. Light is generated in each of the samples at different times consistent with the times at which light is irradiated onto the sample. A single detector is used to detect the lights emitted from the plurality of samples at these different times. A plurality of bifurcated optical cable are coupled to the light emitting devices and single light detector, and the integrated end of each bifurcated cable acts as the light emitting port and light detecting port. Multiple targets can be detected from each of the plurality of samples in the same manner by providing an apparatus and method employing a different plurality of light emitting devices and single detector for each target to be detected.
