Analysis and Revision on Spectra Aliasing of Hadamard Transform Spectral Imager
The principle and instrument structure of Hadamard transform spectral imager is described, and spectra aliasing caused by Hadamard encoding mask is investigated. Spectra aliasing formula is obtained in theory and the method of spectra revision is proposed.Simulation results show that this method is simple and effective. The resolution of spectral images revised depends on space component corresponding to the code which is deviated from optic axis most.
