Problems solved by technology

[0002] In recent years, with the development of science and technology, the requirements for the reliability and accuracy of space cameras in harsh launch environments and space environments have become higher and higher. Space cameras will be subject to vibration and shock during transportation and launch. Complex and changeable, the space gravity field is different from the microgravity environment on the earth's surface. These factors may cause the imaging plane of the camera to not coincide with the focal plane, that is, produce different degrees of defocus, resulting in a decrease in imaging quality

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 As shown, the thermal control focusing device includes a secondary mirror assembly 1, an aluminum ring 2 and a secondary mirror bracket 3. Firstly, the secondary mirror assembly 1 and the aluminum ring 2 are connected together for center adjustment, and the center of the secondary mirror assembly 1 is aligned with the aluminum ring 2 The center is adjusted to the center. Since there is a gap in the middle of the structure between the aluminum ring 2 and the secondary mirror bracket 3 in the thermal control focusing device, there is no center positioning measure, so it is difficult to guarantee the accuracy during installation, and the adjustment is very difficult and costly. It takes a lot of time, the accuracy achieved is not high, time-consuming, and the effect is not good. After connecting the aluminum ring 2 with the second...

Abstract

The invention relates to a thermal regulator focusing assistance adjustment device and method. The device comprises a first adjustment locating ring, a second adjustment locating ring and a mounting and dismounting screw, wherein the first adjustment locating ring is mounted between an aluminum ring and a secondary mirror component of a thermal regulator focusing device; the second adjustment locating ring is mounted on the aluminum ring; the mounting and dismounting screw is located in the middle of the second adjustment locating ring; and the device is convenient to dismount after the aluminum ring and the secondary mirror component are mounted. According to the thermal regulator focusing assistance adjustment device meeting space service conditions and having stable performance, high precision and a reliable structure, and the method, the mounting precision of the thermal regulator focusing device is ensured.

Description

technical field [0001] The invention relates to a thermal control focusing auxiliary adjustment device and method, belonging to the technical field of aerospace cameras. Background technique [0002] In recent years, with the development of science and technology, the requirements for the reliability and accuracy of space cameras in harsh launch environments and space environments have become higher and higher. Space cameras will be subject to vibration and shock during transportation and launch. Complex and changeable, the space gravity field is different from the microgravity environment on the earth's surface. These factors may cause the imaging plane of the camera to misalign with the focal plane, that is, produce different degrees of defocus, resulting in a decrease in imaging quality. [0003] In order to ensure the imaging quality of the camera, it is necessary to add a focusing mechanism to the camera system, use the corresponding focusing mechanism to fine-tune the ...
