Large-aperture off-axis parabolic mirror attitude monitoring control device and method

The invention relates to a large-aperture off-axis parabolic mirror attitude monitoring control device and method. The large-aperture off-axis parabolic mirror attitude monitoring control device specifically comprises an off-axis parabolic mirror, a cooperative reflector, an electric guide rail, an attitude monitoring unit and a closed-loop feedback control unit. According to the device, main laser is adopted as collimating light, new simulation light does not need to be added, light beam near-field and far-field adjustment of the off-axis parabolic mirror can be directly achieved by means of the relative position relation between the main laser calibrated for the first time and the off-axis parabolic mirror, and the device is simple in light path, small in size and capable of being moved in and out through an electric guide rail. And rapid measurement and resetting of the three-dimensional attitude of the off-axis parabolic mirror can be realized. 本发明涉及一种大口径离轴抛物面镜姿态监测控制装置及方法，具体包括离轴抛物面镜、协作反射镜、电动导轨、姿态监测单元以及闭环反
