Abstract:A kind of concentration sensor is made out based on long-period fiber grating with one head, and resolution values are improved by coating silver film and reducing fibre cladding. This concentration sensor is tested for measuring the concentration shift of CaCl2 NaCl solutions, the resolution values in high concentration and low concentration are above 3. 50(g/L) and 1.96(g/L).
