A new type of a vector hydrophone, a laser adaptive hydroacoustic intensimeter, is investigated. Two identical, spatially separated coil-type sensors are used as a primary receiver of the acoustic signal. The signals received at the sensor output are phase demodulated in a two-channel adaptive holographic interferometer based on two dynamic holograms multiplexed in a CdTe photorefractive crystal. Using a laser intensimeter, the acoustic field formed in a limited volume is studied. The performance characteristics of the intensimeter are determined experimentally; its threshold sensitivity, according to the acoustic field intensity, constitutes 0.1 × 10 -13 W m -2 .

激光自适应全息水声强度仪

研究了一种新型的矢量水听器，即激光自适应水声强度计。两个相同的，在空间上分开的线圈型传感器用作声信号的主要接收器。基于在CdTe光折射晶体中多路复用的两个动态全息图，在两通道自适应全息干涉仪中对在传感器输出处接收到的信号进行相位解调。使用激光强度计，研究了在有限体积中形成的声场。强度计的性能特征是通过实验确定的；根据声场强度，其阈值灵敏度为0.1×10 -13 W m -2。
