摘要：The present invention is an optical sensor apparatus for far- field viewing andimaging as well as for the optical detection and analytical measurement of at least onespecies of analyte in a remotely- positioned fluid sample. The apparatus employs animaging fiber comprising a fiber optic array and a Gradient Index lens; and utilizes aremotely- positioned solid substrate having light energy absorbing indicator ligands onan external surface for reactive contact with individual species of analytes when present ina fluid sample. The optical sensor apparatus is able to view an object and provide animage of the object located at a pre-set optical distance remote from the imaging fiber.The apparatus is also able to detect and identify, qualitatively and quantitatively, one ormore analytes of interest in a flowing solid, gaseous, or liquid sample at remote locationsdistanced from the imaging fiber itself.
