在本研究中，我们制作了一种水下光无线通信装置的原型，该装置在光纤末端直接发送和接收光信号，并尝试通过该装置远程控制水下无人机。由于光纤端面面积很小，由多个激光二极管发出的光被引导到一根带透镜的光纤中，从而使末端的光变亮。此外，在设备中还使用了一根芯径较大的塑料光纤来接收大量的光信号。首先，确定了发射波束和接收波束的轮廓以及各端口输出强度的差异；根据这些结果，调整光纤末端的方向，并将其安装在池底。在配备小型光学无线通信设备的水下无人潜航器的远程控制中，可以通过光学无线通信与池边控制器进行操作，同时检查机载摄像机的图像。无人机可以控制的区域几乎是整个游泳池。
In this research, we prototyped an underwater optical wireless communication device that directly transmits and receives optical signals at the end of an optical fiber, and try to remotely control an underwater drone by the device. Since the area of the optical fiber end face is very small, lights emitted by multiple laser diodes are guided into one optical fiber with lens to brighten the light from the end. In addition, a plastic optical fiber with a large core diameter is used for receiving many optical signals in the device. First, the profile of the transmission beam and receiving beam, and the difference in output intensity from each port of the beam combiner were confirmed. Based on these results, the orientation of the end of the optical fibers are adjusted and installed on the bottom of the pool. In the remote control of the underwater drone equipped with a small optical wireless communication device, it was possible to operate with the poolside controller while checking the image of the onboard camera via optical wireless communication. The area where the drone could be controlled was almost the entire pool.
