Underwater target laser line scanning imaging device

Abstract

A scan imaging device for the water object includes the laser in the shell with the transparent window under the water, the laser shot device composed by the extender lens, the plano-concave cylinder lens and the holophote, the receiver in the shell with transparent window and the image processing unit in the water. The electropult and the receiver are separately in the same base plane. The emitting optical axis, the receiving optical axis of the adjusted receiver and the object center are in the same plane. It is loaded on the robot or the ship in the water by the diver and generates the standard image signal to get the clean image. So it can be used for the military and the scientific research.

Description

technical field [0001] The invention belongs to an underwater laser imaging device, in particular to an underwater target laser line scanning imaging device. Background technique [0002] In the existing underwater laser imaging technology, the backscattering problem in the underwater laser propagation process is mainly solved, and the range gating method and the flying line scanning method are usually used. Although these two technologies have achieved gratifying results in underwater detection, there are still many shortcomings. The original devices used in range gating and flying line scanning devices are relatively complex and expensive, and the volume, weight, and energy consumption of these two devices are large, and they can only be used on large underwater vehicles. Therefore, the current underwater laser imaging The technology still cannot achieve the purpose of miniaturization, integration and practicality.

AI Technical Summary

Problems solved by technology

The original devices used in range gating and flying line scanning devices are relatively complex and expensive, and the volume, weight, and energy consumption of these two devices are large, and they can only be used on large underwater vehicles. Therefore, the current underwater laser imaging The technology still cannot achieve the purpose of miniaturization, integration and practicality

[0003] However, the flying line scanning technology developed in recent years mostly adopts the synchronous scanning method. It is difficult to maintain strict synchronization between the emitting laser and the optical polyhedron receiving the light, and the scanning mirror is complicated, the cost is high, and the imaging process is difficult.

These reasons have greatly affected the promotion and use of laser flying line scanning
