A liquid crystal modulator (22), receiving optical energy from a remote source (50) through a fibre optic cable (48) modulates the optical energy in response to an electrical signal from transducer(s) 10. The optical signal is transmitted to utilisation apparatus (62) through a fibre optic cable (52, 60). In a preferred embodiment a piezoelectric hydrophone transducer (10-16) generates an electrical signal in response to acoustic stimulus. The optical signal may be multiplexed, using passive optical techniques, with other optical signals produced by like piezoelectric-liquid crystal hybrid devices. <IMAGE> |
