Abstract

The present invention provides a real -time acquisition device for underwater difference polarizers, involving the field of underwater imaging equipment technology, including imaging unit, which is set up above the imaging unit with a light source, which is set up in front of the light sourceThere is an electronic control polarization unit in front, which includes image sensors, microcontrollers, synchronous circuits, and image pre -processing modules.The electrical control partial sheet makes the polarization state of the electrical control polarization unit changes with the imaging process.The invention uses an electronic control polarization unit, which can realize a full -solid imaging system. It does not need to change the polarization state by mechanical rotation. Compared with the method of changing the polarization state by mechanical rotation, the structure is relatively simple and more reliability.

Description

Technical field [0001] The present invention involves the field of underwater imaging equipment technology, especially in real -time acquisition devices and methods of an underwater difference polarizing image. Background technique [0002] At present, there are two main technical paths to relieve water from the optical perspective during the optical perspective. Laser distance selection imaging uses high -power narrow pulse laser as a light source, and uses ICCD (enhanced charge coupling device) as an image sensor. The laser lighting system uses the laser lighting system to shoot the target area. With the target reflection light, the radiation pulse that reflects the target reflection just reaches the camera and imaged within the camera. Laser distance selection of the imaging system is far from the distance, and the back of the scattering is good, but the system is large, which is not conducive to miniaturization. The ICCD output image has a low signal -to -noise ratio, the ima...
