Embodiment Construction

[0024] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0025] Utilize the soft physical property of optical fiber in the present invention, design a kind of specially arranged image-transmitting optical fiber bundle, its input end line array is not strict line array arrangement, but the " product " font arrangement of multi-layer stacking (such as figure 1 shown). The input end of the fiber bundle is placed on the focal plane of the scanning imaging system, the image is coupled by the fiber bundle, and a small-scale area array device with reliable performance is used to receive information at the output end of the fiber bundle. The line / plane transformation realizes the detection function of the ultra-long line infrared detector.

[0026] The special-shaped image-transmitting optical fiber bundle i...

Abstract

The invention discloses a high resolution imaging method which makes use of specially arranged optical fiber beams to realize the line/face space conversion and adopts an area array detector to realize the detection function of a linear array detector; an input end linear array of the optical beam of the invention is not a regular linear array but is a layer-superposed linear array in the shape of 'Pin' of a Chinese character; when in image scanning, the image information received by the area array detector is separated when an object image sequentially passes each optical fiber so as to obtain a plurality of digital images. The invention not only fully utilizes the information contained by a plurality of digital images but also enhances the SNR of the object image.

Description

Technical field: [0001] The invention relates to a high-resolution image imaging method, in particular to an integral processing method for a digital image obtained by coupling a special-shaped image transmission fiber bundle in an ultra-high-resolution photoelectric imaging system. Background technique: [0002] The design and processing of the ultra-long line detector is the core technology of the ultra-high resolution infrared imaging system; under the condition of a certain field of view, the number of photosensitive elements of the line detector directly determines the spatial resolution of the image: the more elements , the image resolution is higher, but the processing of long-line detectors is difficult, and its research progress is slow due to various factors. At present, only a few countries have mastered it: the detector used in orbit in the United States has reached 6114 yuan, and the French Sofradir has successfully developed The 3000 yuan mid-wave infrared detect...
