    • A light communication system, a transmitter and a receiver are provided. The light communication system includes the transmitter and the receiver. The transmitter has a first processing unit and a light-emitting element. The first processing unit produces a transmission signal. The light-emitting element produces light to carry the transmission signal. The receiver has a first variable lens, a photosensitive element and a second processing unit. The first variable lens changes the propagation path of the light. The photosensitive element senses the light passed through the first variable lens to produce a receiving signal. The second processing unit controls the first variable lens based on the signal quality of the receiving signal to change the equivalent channel between the transmission signal and the receiving signal. Therefore, the transmission capability of the light communication system is enhanced.
    • 提供光通信系统,发射机和接收机。 光通信系统包括发射机和接收机。 发射机具有第一处理单元和发光元件。 第一处理单元产生传输信号。 发光元件产生光以携带传输信号。 接收机具有第一可变透镜,感光元件和第二处理单元。 第一可变透镜改变光的传播路径。 感光元件感测通过第一可变透镜的光以产生接收信号。 第二处理单元基于接收信号的信号质量来控制第一可变透镜,以改变发送信号和接收信号之间的等效信道。 因此,提高了光通信系统的传输能力。
