Abstract:
A sample measuring and analysis system comprising:(a) an optical channel selecting apparatus comprising: (i) an optical input selection device defining a first optical path, the first optical path running between a first input end and a first output end, and the first output end rotatable about a first central axis to a plurality of first index positions defined along a first circular path; (ii) an optical output selection device defining a second optical path, the second optical path running between a second input end and a second output end, and the second input end rotatable about a second central avis oriented in non-collinear relation to the first central axis to a plurality of second index positions defined along a second circular path; and (iii) a controller element communicating with the optical input selection device and the optical output selection device for selectively aligning the first optical path with the first index positions and the second optical path with the second index positions; (b) a plurality of optical source lines corresponding to the plurality of first index positions and selectively communicating with the first optical path; (c) a plurality of optical return lines corresponding to the plurality of second index positions and selectively communicating with the second optical path; and (d) an optical signal receiving device optically communicating with the second output end.
