Abstract
An apparatus for detecting a material within a sample includes a light emitting unit for directing at least one light beam through the sample. A plurality of units receive the light beam that has passed through the sample and performs a spectroscopic analysis of the sample based on the received light beam. Each of the plurality of units analyze a different parameter with respect to the sample a provide a separate output signal with respect to the analysis. A processor detects the material with respect each of the provided separate output signals.
