Description

Technical Field

[0001] This invention relates to the field of aerospace technology, and in particular to a dual-band array detector and an aerial camera that supports allometric image shift compensation. Background Technology

[0002] During reconnaissance, reconnaissance aircraft need to fly at high speed and low altitude to evade enemy radar surveillance. Low-altitude, high-speed flight greatly improves the aircraft's battlefield survivability and deep reconnaissance and surveillance capabilities. However, this results in severe image shift on the target surface during aerial imaging, leading to blurred aerial images. The presence of image shift significantly affects camera image quality, causing a marked decrease in the resolution of aerial photographs. When image shift exists, the captured target outline is unclear, and there is a transition zone of varying sizes between the target and the surrounding background. This transition zone expands as the image shift increases, and when it reaches a certain extent, it can cause the images of adjacent targets to overlap or even become indistinguishable. During forward flight, due to the aircraft's own attitude adjustments (such as side-flying) or the adjustment of the aerial camera lens's pitch angle, the aerial camera is positioned... Figure 1 The oblique viewing working state is shown. A schematic diagram on the target surface is shown below. Figure 2 As shown, its characteristic is that the image movement direction of pixels on the target surface is the same, but the magnitude of image movement varies in different pixel regions. This type of image movement is called allometric image movement. Aerial cameras have significant technical and tactical importance for oblique-view operations, therefore, allometric image movement occupies an important position in aerial image movement.

[0003] In the early 20th century, the American Reconnaissance / Optics Company solved the problem of implementing electronic step-shift image shift compensation on a chip (on-chip compensation for heterogeneous image shift). Based on this technology, they developed the third-generation CCD camera with a frame-shift imaging method. This technology divides the field of view for ground imaging into several regions, ensuring that the image shift velocity in each region matches the line frequency of the CCD, and using the CCD's delay integral to compensate for the image shift in that region. Currently, a series of photoelectric frame-shift cameras have been developed, including the CA-260, CA-261, CA-265, CA-270, and CA-295. Among them, the latter three cameras represent a high level of technological development in dual-band frame-shift cameras. These cameras have implemented electronic step-shift image shift compensation on-chip using a visible light area array CCD chip.

[0004] However, existing CCD cameras only support one of the two imaging methods: visible light imaging or infrared imaging. In some cases, a single imaging method cannot meet the actual needs. For example, the imaging effect of visible light imaging is very poor at night and in bad weather. CCD cameras that only use visible light imaging cannot obtain high-precision images. Summary of the Invention
