Embodiment Construction
[0036] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0037] see Figure 1-Figure 2 , the light and small space laser communication terminal coarse tracking device provided by the present invention includes an optical transceiver 1, a two-degree-of-freedom flexible hinge 2, an azimuth axis actuator 3 and a pitch axis actuator 4 with equal load inertia, a first electric An eddy current displacement sensor 5 , a second eddy current displacement sensor 6 and a base 8 .
[0038] The optical transceiver 1 is installed on the base 8 through the two-degree-of-freedom flexible hinge 2, and the rotation center of the two-degree-of-freedom flexible hinge 2 coincides with the rotation center of the optical transceiver 1; the flexible axis cutting surface of the two-degree-of-freedom flexible hinge 2 can be parabolic, double Curve type, cartwheel type, etc.; in order to take into account the tilt angle range and angular accuracy, ...
