双方向機能を持たせた中継装置用受光モジュールの提案 － 音声送り返しを考慮した映像水中伝送用自律受光モジュール－

抄録

We propose an optical transmission system for realizing TV live broadcasting from a submarine to a ship via a repeater that has receiver modules on its spherical surface. We made a small and stable optical module that can track incident light with wide range , and can send the submarine voice message，too.
