Title:
SPECTRAL RECONSTRUCTION METHOD AND APPARATUS, AND SPECTROGRAPH, STORAGE MEDIUM AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/221588
Kind Code:
A1
Abstract:
A spectral reconstruction method, comprising: by using an objective function, converting, into a positive spectral numerical value, a negative spectral numerical value in spectral data to be processed, such that the anti-noise capability in an iterative solving process of the objective function is improved, and thus the accuracy of obtained reconstructed spectral data is improved. In addition, the spectral reconstruction method does not require the addition of constraints to the objective function, thereby avoiding the conversion of a non-constraint problem into a constraint problem, further improving the accuracy of the obtained reconstructed spectral data, improving the convergence efficiency of the objective function, and also solving the problem of the poor anti-noise capability of the spectral reconstruction method. Further disclosed are a spectral reconstruction apparatus, and a spectrograph (1000), a computer-readable storage medium and an electronic device (1600).
