%X Based on the principle and characteristic of the aperture static imaging spectroscopy(LASIS),the transmission of radiant energy in optics system is analyzed,the radiant energy signal and noise signal received by detector are deduced in detail,and by which the expression about SNR of LASIS is given.In experiment,integrating sphere be used as radiant source,collecting image datum,the actual SNR of LASIS is figured out.The results show that the actual SNR curve fit in well with the deduced SNR curve,the feasibility which using the expression of SNR to estimate the SNR of LASIS is validated.
