Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, an optical system combining laser-induced acoustic underwater communication and laser ranging, the system includes a laser ranging transmitter 1, a laser communication transmitter 2, a shared zoom system 3, a laser ranging receiver 5, a control device 6, data processing system 7, motor 8 and two-in-one multiplexing optical fiber 9.

[0018] The ranging light emitted by the laser ranging transmitter 1 and the communication light emitted by the laser communication transmitter 2 are optically coupled to two branches at one end of the two-in-one multiplexing optical fiber 9 respectively, and are recombined through the two-in-one multiplexing optical fiber 9 One path is used as the light source output, and then jointly exit through the shared zoom system 3, and finally focus on the far-field sea level or a specific laser breakdow...

Abstract

The invention discloses an ocean-wave height adaptive underwater communication system for a communication range-finding common optical system, belongs to the field of spatial laser communication, andaims at solving problems that the adaptive adjustment of ocean waves cannot be achieved in the prior art, a laser range-finding module and a communication module are independent, the size and weight are large, and the structure is complex. The range-finding light emitted by a laser range-finding emitter and communication light emitted by a laser communication emitter are combined by a two-in-one composite optical fiber into one light source for output, and then are outputted through one common zooming system, and are finally focused at a far-field sea level or at a specified laser breakdown depth position below the sea level. The range-finding light beam is reflected by the sea surface, and the laser range-finding receives the light signal and converts the light signal into an electric signal. The electric signal is transmitted to the data processing system for calculating the height of the sea level in real time, and then the information is fed back to a controller. The controller drives the motor to change the focal length of the common zooming system, thereby adjusting the focus position of the laser range-finding light beam and the laser-excited underwater communication light beam, and forming closed-loop control.

Description

technical field [0001] The invention belongs to the field of space laser communication, and in particular relates to an underwater communication system with a wave height self-adaptive communication and distance measurement shared optical system. Background technique [0002] Submarines are an important part of modern military power. Concealment and safety are the main goals of submarine communication in the aerospace field. Laser-acoustic underwater communication technology combines the small transmission loss of infrared laser in the atmosphere and the attenuation of sound waves in seawater It has a small advantage and has broad application prospects in the field of underwater communication. [0003] Laser-acoustic communication uses aerospace platforms equipped with high-power infrared lasers. The modulated laser signals emitted by the aerial platforms are focused under the sea surface and excite acoustic signals. Voice communication. In order to ensure the highest phot...
