| 中文摘要 | 根据激光多普勒测振技术进行声光通信的工作原理,设计一种新型、小型激光多普勒测振信号鉴频电路。该电路根据外差探测原理,本地振荡器输出信号与探测信号混频得到一路信号,经90°移相后的本地振荡器输出信号再与探测信号混频得到另一路信号,利用这两路信号得到了多普勒频移量和声源振动的频率。利用扬声器激发的水面模拟振源进行实验,表明该电路可有效测量的振动频率范围为300 Hz~10 kHz,证明可用于水下光声通信。; According to the principle of the acousto-optic communication with the technique of laser Doppler vibration, a novel and compact circuit of frequency discrimination for laser Doppler vibration signal is proposed. Based on the principle of heterodyne detection, one signal is produced by the local oscillator signal mixing with the detected signal and the other signal is produced by 90° phase-shifted local oscillator signal mixing with the detected signal. These two signals are used to acquire the Doppler shift and the sound source frequency. The measurable vibration frequency range can be up from 300 Hz to 10 kHz with the simulating acoustic sound source, and it can be used for the acousto-optic communication. |
