Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0047] The present invention first prepares the odd-numbered position filter and the even-numbered position filter with the same characteristics as the face-end arrangement by measuring the face-end arrangement of the field-of-view synthetic fiber bundle, that is, the odd-number-position filter corresponds to the face-end of the field-of-view synthetic fiber bundle The optical fibers in odd positions in , and the filters in even positions correspond to the optical fibers in even positions in the field of view synthesis fiber bundle end, such as Figure 4a , 4b and 4c; secondly, use the prepared odd-even filter to calibrate the position of each optical fiber and detector; finally use the distribution coefficient of each optical fiber energy on the detector pixel obtained from the calibration to establish an imaging relational equation, and solve...

Abstract

The invention provides a data recovery method based on an optical fiber field-of-view synthetic spectrum imager. Firstly, the distribution condition of optical fiber surface ends is obtained through an image processing method, odd optical filters and even optical filters which are distributed same as the optical fiber surface ends are obtained by adopting an optical filter etching method; then, auniform light source, the odd optical filters and the even optical filters are used for obtaining detector data not interfered by adjacent optical fiber radiation, and the data is used for solving theenergy distribution of the optical fibers on each detector; finally, an imaging equation of an optical fiber input signal and a detector output signal is established by using an imaging relationshipof the field-of-view synthetic optical fiber spectrum imager, it is achieved that the detectors output recovery optical fiber input by solving the equation, and then two-dimensional space and one-dimensional spectral information are reconstructed through optical fiber input radiation signals.

Description

technical field [0001] The invention relates to a data restoration method based on an optical fiber visual field synthesis spectrum imager. Background technique [0002] Spectral imaging data contains two-dimensional spatial information and one-dimensional spectral information. Due to the two-dimensional spatial characteristics of the detector, traditional spectral imagers can only acquire two-dimensional data at the same time. In order to obtain complete three-dimensional data, it generally takes a certain amount of time to accumulate . This makes transient phenomena impossible to observe using conventional spectral imaging techniques. [0003] With the development of spectral imaging technology and the expansion of spectral application range, the characteristic measurement, target recognition and tracking of moving targets have become important applications of spectral imaging technology. In order to meet this demand, various video spectral imaging technologies suitable ...
