When in the working mode of the working light source, the working light source is coupled to the H-S wavefront sensor. It is necessary to ensure that the environment in the optical cabin is ultra-clean and the cooling air flow is constant. When switching to When debugging the working mode of the light source, it is necessary to couple the debugging light source outside the optical cabin to the H-S wavefront sensor in the optical cabin. The current coupling method is to open the optical cabin wall and add a plane mirror in the optical cabin to complete the debugging of the light source. Coupling jobs.

At present, the switching of the two light source working modes, as shown in Figure 12, includes the reflector 23, the optical cabin 24 and the ordinary mirror frame 26, which is manually put into the ordinary mirror frame, and according to the H-S wavefront sensor The CCD image is used to debug the light source coupling debugging. This method has the following problems: first, the ordinary mirror frame 26 needs to be manually placed, and the side wall of the optical cabin needs to be disassembled, which will directly destroy the ultra-clean environment in the optical cabin. Second, The bottom plate in the optical cabin is provided with replacement air holes, so the ordinary mirror frame 26 cannot be fixed on the bottom plate, but can only be placed statically. It may be necessary to manually adjust the position and angle of the ordinary mirror frame 26 repeatedly, and the efficiency of coupling debugging is low. Third, the ordinary mirror frame 26 is directly placed on the bottom plate in the optical cabin 24, and there is a risk of damaging the precision micro-sized air extraction holes on the bottom plate. , even if the very small quality polytetrafluoroethylene is used as the frame material at present, it is still difficult to avoid a certain degree of damage to the air hole. Fourth, when switching to the working mode of the working light source, after the ordinary frame 26 is manually taken out, The disassembled optical compartment side wall panels need to be reinstalled. The cover panels are heavy and the operating space is small, requiring the cooperation of multiple people to complete the operation.

In this embodiment, the electric drive is used to automatically switch the working mode, and the electric correction is performed at the same time. It only takes about one minute to complete the switching. Move to the left, the angle between the flip frame 2 and the support frame 1 becomes smaller, and the motor 1 4 and motor 2 10 rotate according to the number of control pulses to realize the quantitative adjustment of the pitch and lateral flip movements. In the coupling of the pitch direction, after the device completes the first calibration , through the self-locking function of the worm gear and worm assembly 12, it can be used repeatedly. In the lateral flip coupling, through the action of the mechanical limit module 16, the first horizontal flip movement to an included angle of 45 degrees is rotated according to the number of control pulses to complete the first time. After calibration, record the number of pulses, and set the recorded pulse number as the flip coupling value, which can meet the automatic switching from 0° to 45° flip. When returning to the 0-degree flip direction, the automatic switching of the flip frame 2 from 45° to 0° is controlled by the signal of the photoelectric sensor 18;

In addition, the reduction ratio of the selected worm gear assembly 12 is 1:30, the reduction ratio of the harmonic reducer is 1:100, a 64 subdivision controller is selected, and a stepping motor with a resolution of 1.8 degrees is selected for the motor 2 10, so that the pitch The adjustment accuracy has reached 0.03375", and the joint cooperation of the motor 1 4, the ball screw 8, the slider 5 and the connecting rod 6 controls the flipping of the flipping frame 2, forming a four-bar mechanism with a moving pair, and the two connecting rods 6 The end rotating shaft and the vertical rotating shaft 3 respectively constitute three rotating pairs, the slider 5 is used as a moving pair, cooperates with the 64 subdivision controller, and the motor 4 selects a stepping motor with a resolution of 1.8 degrees, and the lead of the ball screw 8 is 5mm, then under the condition of one pulse, the translational distance of the slider 5 is 0.00039mm, calculated by the graphic method of the linkage mechanism, when the flipping frame 2 is located near the position of 45 degrees, the accuracy of the lateral flip adjustment can reach 0.07236″, satisfying It meets the high requirements of the adaptive optics system on the adjustment accuracy, and the operation is simple and convenient, which greatly improves the working efficiency and stability of the system, and avoids the operational risks and technical difficulties caused by manual direct installation and debugging of the ordinary mirror frame 26 .

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
