Abstract:
 

For a long time, Hadamard transform spectral imager developed slowly due to the constraints of the encoding

mask. However, with the emergence of MOMES, the digital micro-mirror device can be used to design Hadamard encoding

mask, which provides a new opportunity for the development of Hadamard transform spectral imager. A novel type of DMD-

based Hadamard transform spectral imager is introduced and a new design approach of Hadamard encoding mask is proposed.

The DMD is controlled to divide the width of dispersed spectrum corresponding to the spectral response range according

to the order of S matrix equally, so the cyclic Hadamard encoding mask in space is achieved. Experiment results show

that the spectra obtained from the principle prototype spectrometer has high similarity to the spectra extracted by

radiometer, which proves that the Hadamard encoding mask has excellent modulation of the dispersed spectra.
