| Abstract: | A slim fiber laser vector hydrophone with a sensitivity-enhanced flexed beam configuration was presented to satisfy the demands of the slim vector hydrophone array.The sensitivity and resonant frequency of this configuration was calculated by the elastic mechanics and vibration theory.Compared with some existing configurations,the key factor that influences the sensitivity and resonant frequency was found out and some discussion on enhancing the sensitivity without reducing the resonant frequency was carrie... |
