| 摘要 |
The invention proposes a spectrometer facility comprising at least one main optical radiation collector (18, 21, 36) having a main field of vision (CVP) and at least one main optical fibre (18); characterised in that it comprises an aiming system comprising: at least two auxiliary optical radiation collectors (21, 341-343, 36) each having a separate auxiliary field of vision (CVAi), not coincident with the main field of vision, distributed around the main field of vision; for each auxiliary collector, at least one separate auxiliary optical fibre (341-343) and one separate associated photodetector (321-323). The invention also proposes a spectrometry method comprising the comparison of the intensity of the auxiliary optical radiation collected in at least two separate auxiliary fields of vision, not coincident with a main field of vision for collecting characteristic optical radiation. |
