The invention belongs to the field of design of a focal plane splicing structure of an aerospace optical remote sensor, and discloses a space camera focal plane optical splicing structure. The space camera focal plane optical splicing structure solves the problem that the space between two rows of CCD components of a focal plane mechanical staggered splicing structure is large. The space camera focal plane optical splicing structure comprises at least three CCD components, a right-angle focal plane base board provided with at least three through holes, a CCD grinding pad and at least one small reflector, wherein a hole is formed in the center of the CCD grinding pad, the CCD components are fixed on the outer sides of two right-angle faces of the right-angle focal plane base board through the cooperation of a CCD substrate and the CCD grinding pad, the two rows of CCD components are staggered and installed in a shape like a Chinese character 'pin', the spaces of every two adjacent CCD components in each row are the same, each CCD component corresponds to one through hole, each small reflector is fixed on the inner side of one right-angle face of the right-angle focal plane base board and is located on the lower side of every two through holes in the right-angle face, and each small reflector is installed corresponding to the CCD component on the other right-angle face. The space camera focal plane optical splicing structure is compact in structure, the space between the two rows of CCD components is small, and the imaging quality is high.
Description
technical field [0001] The invention relates to the technical field of focal plane splicing structure design of aerospace optical remote sensors, in particular to a space camera focal plane optical splicing structure. Background technique [0002] The imaging of space cameras is mostly linear array push-broom, and the development trend of space cameras requires them to have a larger field of view. Therefore, in the optical design, it is necessary to design a larger optical focal plane. Due to the influence of other factors, it is impossible to produce a CCD that meets the imaging requirements of a large field of view, and it is only possible to splice multiple CCDs with smaller pixel sizes together for imaging to meet the imaging requirements of a large field of view. [0003] like figure 1 As shown, a piece of CCD3 mainly includes CCD photosensitive area 9, CCD packaging area 10 and CCD holder 11, wherein the size of CCD packaging area 10 is greater than the size of CCD ph...
