光发射装置、光接收装置、无线光通信系统及方法
摘要：
一种无线光通信系统，其包括光发射装置及光接收装置，所述光发射装置能够依据第一正电信号以调制发射第一光信号，能够依据第一负电信号调制发射第二光信号。光接收装置能够接收所述第一光信号并其转换为对应所述第一正电信号的第二正电信号，将所述第二光信号转换为对应所述第一负电信号的第二负电信号，所述光接收装置还用于将所述第二正电信号与所述第二负电信号进行差分处理。本发明还提供一种光发射装置、光接收装置及无线光通信方法。
摘要（英）：

A wireless light communication system comprises a light emitting device and a light receiving device; and the light emitting device can modulate and emit first light signals according to first positive electric signals and can modulate and emit second light signals according to first negative electric signals; the light receiving device can receive the first light signals, can convert the first light signals to second positive electric signals corresponding to the first positive electric signals and can convert the second light signals to second negative electric signals corresponding to the first negative electric signals; and the light receiving device can be also used to perform differential processing of the second positive electric signals and the second negative electric signals. Thepresent invention further provides a light emitting device, a light receiving device and a wireless light communication method.
