本文论述了阿达玛变换成像光谱仪的基本原理,探讨了工作模式和若干设计问题,利用自行研制的实验装置,在可见波段获得了各种透明字形的成像光谱图。采用对称π变换和快速δ阿达玛变换,改善了实验数据的处理方法。 In this paper, the basic principle of Hadamard transform imaging spectrometer is discussed. The working mode and some design problems are discussed. Using the experimental device developed by ourselves, the imaging spectra of various transparent glyphs are obtained in the visible band. The symmetry π transform and fast δ Hadamard transform are used to improve the experimental data processing method.
