Recent articles have claimed a significant S/N advantage of Hadamard transform spectroscopy over Fourier transform spectroscopy. The scanty published data does not support this assertion, and the possibility that the claim is valid in theory is examined. Existing theory, as reported in the literature, is not consistent with the claims made for the technique. The advantages and drawbacks of Hadamard transform spectroscopy are examined in detail.
近期的文章声称哈达玛变换光谱法相对于傅里叶变换光谱法具有显著的信噪比优势。但已发表的数据稀少，并不支持这一论断，因此对该论断在理论上是否成立进行了研究。如文献中所报道的，现有理论与该技术所宣称的内容并不一致。本文详细探讨了哈达玛变换光谱法的优缺点。
