尾流气泡幕图像的像质取决于水下光电探测系统的效率,而光源是影响整个成像系统品质的重要原因。针对这个问题设计了适用于实际水下复杂工作环境的新型激光片光源系统,分析和验证了该片光源的能量利用率及可行性。试验结果表明,该片光源系统解决了成像系统照明问题的同时,避免了在光学系统景深范围内太多的图像层叠。在实验室条件下可以获得较清晰的图像,为后续的气泡幕物理参数的精确获取创造了重要的条件。这种光源的独特优势使其在水下小视场光学系统中得到很好的应用。
The quality of the wake bubble image depends on the efficiency of the underwater photodetection system, which is an important factor that affects the quality of the imaging system. In view of this problem, a new laser light source system designed for practical underwater complex working environment is designed, and the energy utilization rate and feasibility of the light source are analyzed and verified. The experimental results show that this light source system can solve the problem of imaging system illumination while avoiding too much image layering in the depth of field of the optical system. A clearer image can be obtained under laboratory conditions, which creates important conditions for the subsequent accurate acquisition of the physical parameters of the bubble curtain. The unique advantages of this light source make it well used in underwater small field of view optical systems.
