对FT光谱术中应用Hilbert-Schmidt理论复原光谱的讨论
ON THE RECONSTRUCTION OF SPECTRUM WITH HILBERT-SCHMIDT′S THEORY IN FT SPECTROSCOPY
【摘要】 求解积分方程的Hilbert-Schmidt理论应用于红外光谱术,能够获得高分辨率、高信噪比的复原光谱,但由于Hilbert-Schmidt定理对积分核对称性的要求,使对具有非对称核的积分方程的求解变得十分繁琐,并且提高了对计算机运算速度和内存容量的要求。本文讨论在FT光谱术中应用Hilbert-Schmidt理论获得复原光谱时,在满足某些特定条件下,可利用对称核理论求解具有非对称核的积分方程,并给出一个对Hilbert-Schmidt定理的推广。本文介绍的方法,可以方便地实现对高波数段光谱的高分辨率、高信噪比的复原,同时拓宽了求解对称核积分方程的Hilbert-Schmidt理论的应用范围。
【Abstract】 The theory of Hilbert-Schmidt for the integral equations can be applied to reconstruct thespectrum from interferometers. In this paper, some conditions are presented so that an integralequation with an asymmetric kernel can be treated as the one with a symmetric kernel directly.Thismakes it concise to apply the theory of Hilbert Schmidt in FT spectroscopy. Modification ofHilbert-Schmidt’s theorem is also discussed.
