Embodiment Construction
[0032] The present invention proposes a packaging method for the special-shaped ring-shaped focal plane of the new geometric optics model to replace the focal plane rectangular packaging block packaging method, which can realize the segmentation of the field of view channel and the segmentation of the field of view, and at the same time ensure that the packaging block fits and installs according to the coordinates .
[0033] The specific steps of the encapsulation method of the optical fiber image transmission beam ring-shaped focal plane are as follows:
[0034] (1) According to the number and size of the required field of view channels, the annular focal plane of the optical fiber image transmission bundle is cut into arc-shaped focal planes of different lengths;
[0035] (2) Using the field of view channel parameters and the inner and outer diameters of the annular focal plane of the optical fiber image transmission bundle, calculate the arc boundary coordinates correspondi...

The invention relates to a packaging method for an annular focal plane of a special-shaped optical fiber image transmitting beam, which comprises the steps of dividing the annular focal plane according to field-of-view channels, calculating boundary coordinates of internal and external packaging surfaces of different arc segments corresponding to the annular foal plane, and laying packaging blocksand an arc-shaped diaphragm so as to perform packaging for the optical fiber beam. The packaging method overcomes a problem that the existing linear optical fiber beam cannot solve effective couplingoutput for the arc-shaped focal plane, can make it possible that a photoelectric system based on a novel geometric optical model is enabled to realize full-field-of-view resolution through a follow-up mature array detector, and truly realizes the quantitative application optical remote sensing products.
Description
technical field [0001] The invention relates to a ring-shaped focal plane packaging method of a special-shaped optical fiber image transmission bundle, which belongs to the field of optical fiber image transmission. Background technique [0002] In the optical remote sensing of the earth, the special-shaped optical fiber image transmission bundle uses its input line array fiber bundle to replace the required long line array detector, and realizes the line-plane conversion output of the imaging effect. The input end of the special-shaped optical fiber image transmission bundle is directly coupled with the imaging focal plane [0003] The special-shaped optical fiber image transmission beam uses its input end line array to replace the required long line array detector, so that the image plane of the telescopic optical system in front of the camera is coupled with the image transmission beam input end. According to the corresponding arrangement, the output end area array passes...
