Problems solved by technology
However, in the face of the new dual-focal plane small and medium-sized space camera with both video imaging and shooting push-broom functions, the dual-focus mechanism mode is cumbersome and redundant, which will not only increase the quality of the camera itself, but also cause the mass of the mechanism to account for too much Big problem, not suitable for the development requirements of light weight and miniaturization of space cameras

The invention discloses a space camera focusing mechanism applied to a conjugate bifocal plane, which belongs to the technical field of space optical remote sensing. The mechanism comprises a base, asliding seat, a worm and gear assembly, a focusing motor, a lead screw nut assembly, a spectroscope assembly, a position information feedback assembly, a push-broom focal plane assembly and a video focal plane assembly, wherein the sliding seat is arranged on the base; the worm and gear assembly is perpendicular to the lead screw nut assembly and is in transmission connection with the lead screw nut assembly; the spectroscope assembly is fixedly connected to the interior of the sliding seat; the position information feedback assembly is arranged on one side of the sliding seat; the push-broomfocal plane assembly is fixedly connected to the upper portion of the sliding seat; and the video focal plane assembly and the push-broom focal plane assembly are perpendicular to each other and are fixedly connected to the side face of the sliding seat. According to the mechanism, the double focal planes are in a conjugate state relative to the spectroscope, so that the function that a single focusing mechanism focuses two imaging modes at the same time is realized.
Description
technical field [0001] The invention belongs to the technical field of space optical remote sensing, and in particular relates to a space camera focusing mechanism applied to a conjugate bifocal plane. Background technique [0002] Due to the impact of changes in the carrying environment, launch conditions, and space environment, the focal plane will shift, that is, defocus. In order to ensure clear imaging, the space camera must have a precise focusing function. At the same time, due to the task requirements of dual shooting modes in some spaces, cameras need to arrange dual focal plane electric boxes. In order to meet the focusing needs of double electric boxes, the traditional mode needs to configure a focusing mechanism for each focal plane electric box. This mode The lower two mechanisms are independent of each other, and each has a separate focusing function. However, in the face of the new dual-focal plane small and medium-sized space camera with both video imaging ...
