| Summary: | 0.38% (250 i)], and the range [0.44% - 0.97% (300 i)] 0.3dB - 0.4dB for the 3001 coating. Two perturbations A new design of fiber optic hydrophone sensor arrays phics. are applied to fiber optic hydrophone sensor arrays in controllable low reflectance range less than 1.0%, the fiber end. Three different coating thicknesses of the fibers is investigated. The mirrors are produced by forms of acoustic excitation, one generated by a fusion arc splicing of two fibers, one of which has a hydrophones was confirmed in these tests. internal mirrors was tested in a water tank using two machine was used for producing a coating on a cleaved range [0.034% '-' 0.054% (150 i)], the range [0.13% - reflectance internal mirrors were tested. For the semiconductor laser light source and a photodiode. speaker in air and the other by a wave in the tank. splicing process. The measured optical excess loss was The feasibility of time division multiplexing of the The hydrophones were monitored using a pulsed the water tank. A six hydrophone array using the thin film of TiO2 on the end. A magnetron sputtering TiO2 material [(150 i, 250 h, and 300 i)] for the low using low reflectance internal mirrors in optical were obtained by varying the parameters of the |
