Disclosed is a single-axis rotational inertial navigation system based on bidirectional optical communication and wireless power supply. The system comprises a bidirectional optical communication unit, a wireless power supply unit, a motor driving unit, an inertial measurement unit, a rotating-end information acquisition and processing unit, and a fixed-end information receiving and processing unit. According to the system, in the same transmission channel, information interaction between a rotating end and a fixed end is achieved by adopting infrared light communication and visible light communication; and medium-power high-efficiency wireless energy transmission under a specific distance is achieved by adopting a magnetically coupled resonant wireless power supply method. The design of a high-accuracy motor driving unit is achieved by adopting the design of combining a frameless torque motor with an incremental circular grating and double reading heads.
