摘　　要：光纤傅里叶变换光谱仪(FFTS)干涉图的采样方式一般有两种,即单边采样方式和双边采样方式。详细介绍了在两种不同采样方式下的光谱复原技术,给出了数学表达式和计算过程,比较了两种算法的优缺点,并对单边复原算法进行了改进,提高了使用乘积法进行相位校正的效率。对研究结果进行了实验验证,用两种算法计算得到的复原谱与标准谱线进行比较,二者基本重合,证明了算法的有效性。 ,There are two types of sampling to obtain fiber Fourier transform spectrometer （FFTS） interferogram, single-sided sampling and double-sided. The techniques for obtaining recovered spectrum from the two types of interferogram sampling are discussed in detail. The mathematical expressions and calculation procedures are proposed. The advantages and shortcomings of each technique are compared. The single-sided recovery algorithm is ameliorated and the phase correction efficiency is improved. The research results are proved through the experiment. The recovered spectra by two algorithms agree well with the standard spectrum, which proves the methods are effective.
