Abstract
An inline spectroscopic reader having a light source, one or more optics heads, a spectrometer and a data processing system in digital communication with the spectrometer detector. The optics heads include transmission optics providing for the illumination of a target with light from the light source and detection optics providing for the collection of light from the target. Typically, the target is moving with respect to the optics head during spectroscopic interrogation. The spectroscopic reader is thus an inline reader well suited to provide spectrum based production or analytical decision making in real time as the target moves along a production or analysis line. Also disclosed are methods including the steps of illuminating a target with light from a light source; collecting light from the target; obtaining a digitized spectrum with a spectrometer; extracting information content from the digitized spectrum; and basing a contemporaneous process decision upon the information content.
