An underwater laser circumferential scanning detection device and system

Abstract

An underwater laser circumferential scanning detection device and system belong to the field of underwater target detection. The detection device of the present invention includes a laser, a casing, a beam emitting component, an echo receiving component and a processor. The shell is equipped with a beam emitting component and an echo receiving component, and is provided with a one-to-one corresponding exit window and receiving window. The beam emitting assembly includes a diverter located in the center of the assembly and a plurality of emitters arranged in a circle and one end of which is spliced ​​and closed. The underwater laser circumferential scanning detection device provided by the present invention has no circumferential detection blind area, and the receiving and receiving light path occupies less area, has a compact structure and high strength, is easy to connect with the front and rear compartments of the underwater vehicle, and is suitable for the azimuth of the underwater circumferential target , Distance fine detection.

Description

technical field [0001] The invention relates to the field of underwater target detection, in particular to an underwater target circumferential scanning laser detection device and system. Background technique [0002] Underwater target detection technologies mainly include underwater acoustic detection, magnetic field detection, electromagnetic detection and laser detection. Underwater acoustic detection adopts active or passive methods to obtain the sound field information of the target, but its detection performance is easily restricted by various acoustic decoys, acoustic interference, environmental interference and noise reduction technology, and it is difficult to guarantee its detection reliability. Magnetic field detection senses the presence or absence of a target based on the abnormal changes in the surrounding magnetic field when the target appears. Its operating range is small (usually less than 1 meter), and its positioning accuracy is poor, which cannot meet the...

AI Technical Summary

Problems solved by technology

However, the detection device has a circumferential detection blind area because the supporting structure blocks the emitted beam, and the large-area optical path channel and optical window also destroy the structural connection strength and sealing pressure resistance of the device

[0005] To sum up, there is currently a lack of an underwater target circumferential scanning laser detection device suitable for small carrier volume and limited power consumption, which has no circumferential detection blind zone and can meet the requirements of structural connection strength and sealing pressure resistance.
