Some commercially available fiber optic sensors though in small quantities are being used for automation in mechanical and industrial environments. They are also used for instrumentation to measure and control various optical properties. In the present work, an intensity modulated intrinsic fibre optic sensor is used to study various characteristic properties of beryllium chloride thin film coated micro-slides using optical fibre probes. Chemical bath deposition technique is used to grow thin films with the solutions of beryllium sulphate, Sodium hydroxide and potassium chloride. Sodium hydroxide serves as complexing agent. Beryllium sulphate acts as source for Be2+ions and sodium chloride acts as source for Cl- ions. Beryllium chloride films were grown at different deposition times and at different concentrations. Various optical characteristics are studied using fibre optic sensors operated at various wavelengths. | | Keywords : | | |
