Analysis of Corresponding Changes of two Dimensional Hadamard Spectral Images Caused by Imperfect Encoding Templates and Their Position Errors

Errors of encoding templates cause their S cyclic matrices change,and encoding templates with errors of different types form different S cyclic matrices.Based on the encoding and decoding principles of Hadamard Transform Imaging Spectrometer,the changes of two dimensional spectral images are obtained and analyzed by comparing the decoded spectral images with the original spectral images,when the encoding templates have errors of different types.The relationship between the changes of spectral images and the errors of the encoding templates are obtained.This one will contribute to the calculation of the total errors and can be a reference for errors control.
