Problems solved by technology

[0005] The disadvantages of this flexible structure are: a) The flexible link can effectively reduce the thermal stress in the transverse (radial) direction, but cannot reduce the thermal stress in the longitudinal (axial) direction, and cannot be used to support large-diameter optical lenses with higher performance requirements ; b) The outer frame connected to the flexible link is too bulky, which reduces the quality utilization rate of the flexible link; c) The internal convex structure of the flexible link has no longitudinal limit, and a longitudinal limit structure needs to be designed separately, which is not conducive to the ultra-high Position accuracy installation; d) The internal convex structure of the flexible link is connected to the lens through adhesive, and the storage position of the adhesive is not designed, which makes it difficult to control the amount of adhesive used in the actual operation process; d) This flexible structure does not propose the adaptation of mechanical properties Sexuality, which brings difficulties to the engineering application of large-aperture lenses

Abstract

The invention relates to a flexible heat-dissipating and vibration-damping support structure for an optical lens of a space-pointing measuring instrument, which is characterized in that it comprises an inner ring and a fixing flange; Folding arm beam links with both lateral and vertical degrees of freedom release capabilities are evenly distributed between the fixed flanges; the folding arm beam links and the cementing links are staggered; For radial positioning, the axial positioning and connection of the optical lens are realized through the fixing flange.

Description

technical field [0001] The invention relates to the fields of space extremely high-precision pointing measurement technology, space remote sensing and star sensors. In particular, it relates to a flexible heat-dissipating and vibration-damping support structure for an optical lens of a spatial pointing measuring instrument. Background technique [0002] The lens is the core key optical element of the transmissive optical system, and its surface accuracy and stability determine whether the performance index of the entire optical system can meet the design index. With the improvement of optical system resolution, field of view, and aberrations, the aperture of optical lenses is getting larger and larger, and the requirements for the accuracy of the surface shape of a single lens are getting higher and higher. How to reasonably design the support of large-diameter optical lenses The structure is crucial to ensure the overall performance of the optical system. [0003] The tra...
