Abstract

The invention relates to an axial main lens support mechanism for a vehicle-mounted self-adapting optical imaging telescope and belongs to the field of large-diameter self-adapting optical imaging detection. The mechanism solves the technical problems of low inherent frequency and low overall rigidity. The axial main lens support mechanism comprises balance mechanisms, main lenses and a main lens chamber, wherein the balance mechanisms comprise balance components and balance levers; each of the two ends of each balance lever is fixedly connected with one balance component respectively; the balance mechanisms are uniformly distributed and fixedly connected into the main lens chamber circumferentially via column articulation components and the balance levers; and the main lenses are located on the balance mechanisms. The mechanism is compact in structure, good in system rigidity, high in structural space utilization rate, small in assembly stress and high in locating accuracy, and surface shapes of the main lenses have small influence.

Description

technical field [0001] The invention belongs to the field of large-aperture self-adaptive optical imaging detection, and in particular relates to a main mirror axial support mechanism for a vehicle-mounted self-adaptive optical imaging telescope. Background technique [0002] The main mirror support system of the meter-class vehicle-mounted adaptive optics imaging telescope usually adopts a passive support mechanism due to its cost and reliability requirements. Its support system needs to maintain the accurate position and good surface shape of the primary mirror in its working state, and at the same time, it needs to have good support rigidity due to its vehicle-mounted conditions. For the overall design of the mirror support mechanism, it is necessary to consider the principle of rigid body statics to meet the static requirements of the support system, that is, the degree of freedom of the support system is 0; the local design needs to consider the micro elastic deformatio...
