Problems solved by technology
The existing underwater Raman system is mainly for the composition detection of underwater targets. The detection results can only reflect the composition information of the target object, but cannot describe the shape characteristics of the target object. A lot of useful information will be lost in the detection

[0060] In other embodiments, the positioning mechanism 3 can provide different displacement strokes by changing the lengths of the screw 3.4, the sliding rail 3.6 and / or the moving push rod 3.7.
[0061] It should be noted that the interior of the positioning cabin 3.2 is filled with silicone oil to achieve the effects of waterproofing, heat conduction and lubrication. In addition, the outside of the positioning cabin 3.2 is also provided with a pressure compensator 3.1 that communicates with the inside of the positioning cabin 3.2. The pressure compensator 3.1 is a flexible oil-filled rubber bladder, which is communicated with the positioning cabin 3.2 through a flange interface for balanced positioning. Internal and external pressures of cabin 3.2.
[0062] The underwater detection system adopts the servo motor 3.3 to drive the screw rod 3.4 to rotate, and then the screw rod 3.4 drives the ball slide table 3.5 to move to realize the large stroke displacement with micron prec...

The invention discloses an underwater Raman probe and an underwater detection system. The underwater Raman probe includes a Raman probe, a reflector, a beam splitting prism, a microscopic objective lens and a window arranged in sequence along the laser emitting direction; and a self beam splitting prism A tube lens and a microscopic imaging camera are arranged in sequence along the imaging circuit; a beamsplitter prism is used to couple the Raman optical path and the imaging optical path to form a coaxial optical path structure; the imaging optical path and the spectrum acquisition optical path share a microscopic objective lens as an imaging objective lens and an optical focusing lens respectively . The detection system includes an underwater Raman probe, a positioning mechanism and a control mechanism. The invention combines Raman spectroscopy with microscopic imaging to form an underwater Raman probe, and uses a positioning mechanism to drive the underwater Raman probe to move with high precision in a large range, so as to cope with the ups and downs of the underwater terrain and improve the definition of imaging and detection accuracy.
Description
technical field [0001] The invention relates to the technical field of underwater detection, in particular to an underwater Raman probe and an underwater detection system based on microscopic image assistance. Background technique [0002] The marine environment is complex and dynamic, with multiple biological, chemical and physical processes coupled and interacting with each other. It is difficult to conduct these studies in the laboratory because such complex natural systems cannot be fully simulated. In situ research under natural conditions also faces a series of challenges. The complex and changeable external environment puts forward strict requirements on the stability and robustness of observation equipment. Influence, the conclusion of the study often needs to be corroborated by a variety of different sensor data. In the past few decades, researchers have developed various underwater detection devices for different underwater detection targets, but these devices usu...
