ENCODING CONFIGURATION DESIGN & DECODING ALGORITHM OF AN ENCODING IMAGING SPECTROMETER

With the use of cyclic S matrix, the cyclic encoding configuration of one dimension two dimension encoding mask have been designed, which make the encoding measuring procedure of the instrument remarkably simplified. A decoding algorithm based on π transform and fast Hadamard transform changes the matrix multiplication to the addition ,subtraction and position exchanging among the matrix elements, so reduces the demand of the instrument for computer.
