A collimating telescope 6 for adjusting the divergence angle of the transmitted beam so that the beam can be transmitted at a long distance; the fine tracking system 7 can further adjust the direction of the light beam to achieve the tracking accuracy of the single-mode optical fiber level.
A first reference optical signal transmitted by a target device in a moving state may be received.
Optionally, before the step of receiving the first reference optical signal transmitted by the target device in the moving state, the method further includes:
detecting whether the space angle of the holder driven by the brushless motor changes;
and under the condition that the change of the space angle of the holder driven by the brushless motor is detected, controlling a pitching shaft, a yawing shaft and a rolling shaft contained in the holder driven by the brushless motor to rotate.
It should be noted that, the axes of the yaw axis 1, the pitch axis 2 and the roll axis 3 are all provided with a gyroscope sensing chip, and when the pan-tilt moves relatively with the moving single-mode fiber tracking device, the gyroscope sensing chip can sense the corresponding angle change. Whether the space angle of the holder driven by the brushless motor changes or not can be detected.
Under the condition that the change of the space angle of the holder driven by the brushless motor is detected, the pitch shaft, the yaw shaft and the roll shaft contained in the holder driven by the brushless motor can be controlled to rotate. That is, the 3 axes of the pitch axis, the yaw axis and the roll axis can be driven to rotate by generating control signals through an internal control circuit.

In step 304, a difference between the first position coordinate and the second position coordinate may be calculated, i.e., a difference between the first position coordinate (x1, y1) of the first reference optical signal and the second position coordinate of the zero point position may be obtained.
And 305, adjusting the pitch angle and the yaw angle of the holder driven by the brushless motor according to the difference value so that the absolute value of the difference value between the position coordinate of the first reference light signal and the second position coordinate of the zero position is smaller than or equal to a preset threshold value.
In step 305, the pitch angle and yaw angle of the brushless motor driven pan/tilt head may be adjusted according to the difference value, so that the absolute value of the difference value between the position coordinate of the first reference light signal and the second position coordinate of the zero point position is less than or equal to a preset threshold value. The difference value can be used as an input signal, and the pitch angle and the yaw angle of a holder driven by a brushless motor in the moving single-mode optical fiber tracking device are adjusted through PID control, so that the position of the first reference light signal moves to the zero position. After the PID parameters are reasonably selected, the position of the first reference light signal can be always near the zero position, so that the integral pointing of the holder is ensured.
In step 306, fine tracking can be performed when the transmitted beam needs to be further collected into a single mode fiber. The fine tracking system may include a detector and a deflection mirror. The detector may be a CMOS, CCD or four quadrant detector. The deflection mirror may be a piezo ceramic driven deflection mirror. A second reference optical signal transmitted by the target device may be received.
And 307, controlling the second reference light signal to deflect, so that the deflected second reference light signal is transmitted to a target single-mode optical fiber of the mobile single-mode optical fiber tracking device.
In step 307, the second reference light signal may be deflected by controlling the deflection mirror, so that the deflected second reference light signal is transmitted into the target single mode fiber of the mobile single mode fiber tracking device. At this time, the link between the mobile single-mode fiber tracking device and the target device is established, and light beam transmission can be carried out.
Optionally, after the step of controlling the second reference optical signal to deflect, the method further includes:
receiving a target optical signal, wherein the target optical signal is obtained after a collimating telescope of the target device adjusts a divergence angle of an optical signal emitted by a laser in the target device.
After the link between the mobile single-mode fiber tracking device and the target device is established, the target optical signal can be received. The target optical signal is obtained after a collimating telescope of the target device adjusts the divergence angle of an optical signal emitted by a laser in the target device. It should be noted that the light emitted from the laser is divergent, and only parallel light can be transmitted in the air without much loss. The collimating telescope adjusts the divergence angle of the optical signal emitted by the laser from diverging to parallel.
The application provides a method for moving single mode fiber tracking and aiming, which is applied to a device for moving single mode fiber tracking and aiming.
