Abstract:
1. An optical analytic subsystem comprising: a sensing optical fiber having at least one exposed core region free of cladding and free of sensitive coating or other sensitive, reactive chemical preparation; at least one light source, each having a respective, predetermined output spectrum, the at least one light sources respectively associated with one of the at least one exposed core regions such that energizing the light source engenders a probing light to be transversely directed to side-illuminate the associated exposed core region from outside of the sensing fiber; at least one location, the at least one locations respectively associated with one of the at least one exposed core regions, and at least one of the light sources, the location being adapted to accept inclusion of an analyte, and where the location is positioned relative to the associated exposed core region and to the associated light source's probing light path that, where the analyte has at least one of the properties of the list: chemiluminescence, phosphorescence, fluorescence, scattering, refraction, reflection and absorption, of light at the associated light source's spectrum, the probing light is modified such that a resultant light signal is coupled into the sensing fiber's core and is detectable at a terminus of the sensing fiber such as to identify a measurand of the analyte.
