【摘要】 通过CCD的数据采集对单缝衍射条纹的光强进行测量试验,简要分析了试验中的噪声来源。提出使用小波技术对CCD的采集信号进行噪声滤除,详细讨论了小波的分解与重构以及在去除噪声中的应用。试验结果表明,小波技术能完全滤除噪声。更多还原

【Abstract】 The light’s intensity of single slot diffraction stripes is measured through the data acquisition of CCD detection,the source of noise in the experiment is briefly analyzed.The noise of CCD’s data is filtered with the wavelet technology which is setout in this paper.The decomposing and composing of wavelet and the application of it in denoising are particularly discussed.The result of experiment(indicates) that the noise can be filtered completely by the wavelet.更多还原
