哈达玛变换光谱仪压缩系统研究

摘要

Hadamard transform spectral imager technology based on Digital Micro-mirror Device （DMD） is a new technic.And few paper introduce it at home. This paper has introduced DMD Hadamard transform spectral imaging spectrometer firstly,and points that the unique places which is much better than traditional ones.Secondly, By compressing the original datas sampled from the spectrometer,the high SNR and high resolulion datas are obtained. Finally,the compression method is of good real time ,little distortion and high practical value and broad application scope.%基于数字微镜器件（Digital Micro-mirror Device,DMD）的哈达玛变换光谱技术是一种新型的光谱成像技术,在国内很少有专门的文献介绍[1-3]。文中先介绍了本实验采用的哈达玛光谱仪样机的原理以及哈达玛成像光谱仪优于传统模板的独特之处,即获得多通道高能量高信噪比的光谱数据,然后描述对采集到的数据做高信噪比,高分辨率压缩处理,最后说明此方法实时性强、图像失真小、实用价值高、应用范围广。
