Embodiment Construction
[0040] The sonar device of the present invention will be described below with reference to the accompanying drawings and specific embodiments.
[0041] refer to figure 1, The sonar device of the present invention includes laser source array 101, time division / space division / wave division hybrid multiplexer 102, fiber grating type fiber optic hydrophone array 103, interferometric phase converter 104, dense wave decomposition multiplexer 105 , phase generating carrier modem 106 and data generator 107 . Wherein, the multiple laser sources in the laser source array 101 generate laser beam pulses of different wavelengths, and then send them to the time division / space division / wavelength division hybrid multiplexer 102 through an optical fiber; the time division / space division / wavelength division hybrid multiplexer 102 After optically mixing the laser beam pulses of various wavelengths, the mixed laser beam pulses of different timings are irradiated into different line arrays of th...
