%X The spectral correlation and spatial correlation of images from interferential imaging spectrometer is analyzed and calculated.The mixed lossless compression scheme is proposed.This scheme includes three aspects:DPCM between Spectra,Integer Wavelet Transform to prediction error image and adaptive bit-level Arithmetic Coding to Wavelet coefficient.The experimental data shows that the algorithm has carried out lossless compression,the average of compression ratio is up to 2.018.It is increase 40.3% in comparison with Integer Wavelet Transform of two dimensions.This algorithm use addition-subtration and shifts to complete data compression.Implementation with hardware is easier.
