本发明涉及一种基于逆反射的无源光通信装置,至少包括第一控制模块和第一光学传感器,其中,所述第一控制模块配置为控制所述第一光学传感器吸收能量的第一状态和识别光的第二状态的交替变换。本发明通过第一状态和第二状态的交替变化实现接收光信号的离散化进而不需要模数转换器就能实现光信号的数字化,而且通过第一状态和第二状态的交替变化实现吸收能量和接收光信号两个状态的分离以在增加接收光信号可靠性情况下,不仅能够显著降低能耗,还能够通过第一状态保证能量的供给,从而实现长时间的无源工作。

    The invention relates to a passive optical communication device based on retro-reflection, which at least comprises a first control module and a first optical sensor, and is characterized in that thefirst control module is configured to control the first state of the first optical sensor for absorbing energy and the second state of the first optical sensor for identifying light to be alternatelychanged. According to the invention, discretization of the received optical signal is realized through alternate change of the first state and the second state, so that digitization of the optical signal can be realized without an analog-to-digital converter; and the separation of two states of energy absorption and optical signal receiving is realized through the alternate change of the first state and the second state, so that the energy consumption can be remarkably reduced under the condition of improving the reliability of the received optical signal, the energy supply can be ensured through the first state, and the long-time passive work is realized.
