Mirror oscillating wide-format imaging system and imaging method

Abstract

The invention discloses a reflecting mirror swing wide imaging system which comprises a visible light area array imaging camera and a swing reflecting mirror. The swing reflecting mirror is rotationally arranged at the front end of the visible light area array imaging camera. The imaging view field of the visible light area array imaging camera is enlarged by rotating the swing reflecting mirror, so that the visible light area array imaging camera can take multi-angle photos of sub-satellite points in the width direction, and a wide sub-satellite point photo is formed. The swing reflecting mirror discontinuously rotates, stops rotating to be immediately stabilized after rotating by a certain angle and continues to rotate after imaging is achieved by the visible light area array imaging camera, and the steps are repeatedly executed, so that stable and clear imaging is achieved. The invention further provides an imaging method of the reflecting mirror swing wide imaging system. The imaging width is increased on the condition of not upgrading camera configurations, only the swing reflecting mirror is installed, and the reflecting mirror swing wide imaging system has the advantages of being low in mass, low in cost, wide in imaging range, high in resolution ratio, easy to achieve and the like.

Description

technical field [0001] The present invention relates to an imaging technology in the field of aerospace technology, in particular to a mirror swing wide imaging system and an imaging method. Background technique [0002] With the development of aerospace technology, large-scale, fast response, high resolution, and high accuracy have become the technical development requirements for ground imaging and reconnaissance satellites. However, since the current satellite-to-earth imaging width and resolution are severely limited by the configuration of spaceborne cameras, the imaging width of existing imaging and reconnaissance satellites is generally in the range of tens of kilometers to tens of kilometers, which is far from reaching The mission requirements for rapid and accurate search of ground information in emergencies. Therefore, it is very necessary to study the wide-format imaging technology of satellites. [0003] At present, some existing wide-format imaging satellites ...

AI Technical Summary

Problems solved by technology

[0003] At present, some existing wide-format imaging satellites adopt the technical means of using single-point infrared cameras to scan wide-format imaging. The imaging resolution of this method is low; there are also multiple high-resolution cameras for multi-angle stitching of fields of view. Due to the need to carry multiple cameras, high requirements are placed on the satellite platform, which is difficult to implement and high in cost

[0004] The mirror swinging wide-format imaging technology involved in the present invention has not found any technical description or report similar to the present invention, and has not yet collected similar information at home and abroad.
