用于尾流探测的新型片光源

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。

A new illuminating source for the ship wake detection

The quality of bubble image is determined by the efficiency of underwater optical system in ship wake detection,while the illuminating source is an important factor that affects the performance of the underwater imaging system.A new sheet laser source is proposed in order to solve the problem,and the utilization rate and feasibility are analyzed and proved.The test results show that the new illuminating source can not only solve the lighting of the imaging system,but also avoid excess images overlapping within the depth region of the optical field.The proposed light source creates significant terms for acquiring the parameters of the bubble curtain.This new design can be used in under-water optical systems because of its unique advantages.
