摘要
利用希尔伯特-史密特定理解积分方程能得到高分辨率复原光谱。当光谱分布波数范围较大时,将其分为几个小区域,适当选取参数,可大大减小计算点数(～41);当反射率随波长改变时用修正的希尔伯特-史密特定理能进一步减少计算机时间和容量。
Using the theory of Hilbert and Sehmidt, the spectrum is recovered with a high resolution from an integral equation representing the relation between the spectral distribution and its multiple-beam interferogram. The number of calculating points becomes small (～41)by dividing the larger wavenumber into several smaller ones and choosing appropriate parameters. The results also show that after a modification of the theory of Hilbert and Schmidt, both the calculating time and the capacity of a computer are further reduced for the case where the roflectivity of the reflecting surfaces varies with wavenumber.
