介绍一种可有效减小光谱编码测量中的相位误差，提高光谱分辨本领的精细采样方法。基于π变换和快速阿达玛变换（ＦＨＴ），给出了精细采样的解码算法——快速δ阿达玛变换（ＦＤＨＴ）。
A fine sampling method that can effectively reduce the phase error in spectrum coding measurement and improve the spectral resolution is introduced. Based on the π transform and the fast Hadamard transform (FHT), the fine sampling decoding algorithm - Fast δ Hadamard transform (FDHT) is given.
