Abstract

The invention relates to a flexible primary mirror supporting device. The primary mirror comprises two supporting plates, and a plurality of supporting rods arranged between the two supporting plates, wherein each supporting rod comprises a middle rod, two connecting rods arranged at two end parts of the middle rod, and flexible transitional components arranged between the connecting rods and themiddle rod; each flexible transitional component comprises a transitional block, an end part connecting plate and a middle connecting plate; the end part connecting plate and the middle connecting plate are parallel to the axial line of the middle rod and are perpendicular to each other; the other ends of two connecting rods are fixedly connected with the corresponding supporting plates; two L-shaped through slots are formed between the transitional block and the end part connecting plate and the connecting rod; two L-shaped through slots are formed between the transitional block and the middle connecting plate and the middle rod; L-shaped through slots are filled with elastic damping cushions. The technical problem that the primary mirror supporting device cannot isolate the influence ofexternal environment and an installing base on a primary mirror is solved; and through the flexible transitional components, the influence of the structural deformation of the installing base and a heat flow on the primary mirror can be effectively isolated.

Description

technical field [0001] The invention belongs to the technical fields of space detection and astronomical observation, and in particular relates to a flexible supporting device for a primary mirror. Background technique [0002] In the technical fields of space detection and astronomical observation, in order to realize space long-distance target detection and explore the mysteries of the universe, it is necessary to increase the aperture of photoelectric detection equipment to improve the resolution of the system and the target energy of the mobile phone, so that it is easier to find and identify targets . The large-aperture primary mirror in these optoelectronic devices is a key part of the entire device. It is affected by both the external environment and the installation foundation. The surface distortion of the primary mirror caused by these effects will lead to a decrease in the optical quality of the entire device. [0003] The primary mirror support device is used to...
