PHOTONIC MEASUREMENT INSTRUMENT USING FIBER OPTICS |
摘要 |
A photonic measurement system, such as an atomic absorption spectrometer, includes source, sample and detection modules that are interconnected by fiber optic cables. A first set of fiber optic cables guides light from one or more light sources in the source module to each of at least two analysis chambers in the sample module. A second set of fiber optic cables guides light from the analysis chambers to a detector in the detection module. The detector provides to a processing sub-system signals that correspond to intensities of the guided light. One analysis chamber is selected to perform a sample analysis at a given time, and the processing sub-system processes the signals associated with the selected analysis chamber as measurement signals. The processing sub-system may further process the signals associated with a given non-selected analysis chamber as reference signals.
