用改进的Chebyshev函数提高干涉图切趾效果
Improved Chebyshev Function to Raise the Effect of Interferogram Apodization
摘要
Abstract
In order to rectify the shortcomings of high power leakage rate at low side-lobe attenuation and identical fluctuation of side-lobe attenuation of Chebyshev apodization function,an improved Chebyshev apodization function is put forward.Firstly,the defects of Chebyshev apodization function in spectrum restoration is analyzed by simulation;and then,the Blackman-Harris function is selected to improve it and compared with the previous one;at last,the function is used for monochromatic interferogram apodization process and simulation.The simulation results show that the new Chebyshev apodization function can solve the problems of high power leakage rate at low side-lobe attenuation and identical fluctuation of side-lobe attenuation,and its application ability is more flexible.关键词
