Interrogation system of signals from a fiber-optic refractometer

摘要

the system interrogacji signals of optic refractometer is to enable monitoring of the refractive medium, without the impact of changes under the light source.the influence of temperature and the effect of the electromagnetic field.the interrogacji signals of optic refractometer consists of a broadband light source (1) connected by optical fibre jednomodowy (2a) with skou015bnu0105 bragg grid (3),which is connected via a fibre optic cable jednomodowego (2b) with sprzu0119gaczem optical (4).the first exit sprzu0119gacza optical unit (4) is connected through a fibre optic cable jednomodowego (2c) of the first optical cyrkulatorem (5),to which is attached via a fibre jednomodowego (2d) first grid bragg of linearly variable period (7).which go through the first optical cyrkulator (5) is connected via a fibre optic cable jednomodowego (2e) of the first fotodetektorem (9).the second way sprzu0119gacza optical unit (4) is connected through a fibre optic cable jednomodowego (2f) of the second optical cyrkulatorem (6),who, through fibre jednomodowego (2g) is connected with the second grid bragg of linearly variable period (8),which go via the second optical cyrkulator (6) is connected via a fibre optic cable jednomodowego (2h) of the second fotodetektorem (10).
