Embodiment Construction
[0021] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0022] In order to achieve nanometer positioning accuracy in the presence of interference, the flexible displacement actuator of the splicing mirror of the large-scale optical infrared telescope of the present invention adopts a two-stage design of rotational symmetry and series stacking, which combines the coarse adjustment function (long stroke) and the fine adjustment function. Adjustment function (short stroke).
[0023] Such as figure 1 As shown, the flexible displacement actuator includes guide pin 1, lifting output cylinder 2, voice coil motor 3, folding leaf sprin...
