| 摘 要： | 基于Shalvi-Weinstein盲目去卷积标准,提出了一种拉曼光谱盲目去卷积的超指数收敛算法,可以同时从观测数据估计真实光谱数据与仪器的响应函数,且具有超指数的收敛速度.通过实测拉曼光谱数据的试验,验证了该算法的可行性.

| Abstract: | Based on the Shalvi-Weinstein criterion, a super-exponential algorithm for Raman spectra blind deconvolution is proposed. The actual spectral data and the unit-impulse response of measurement instruments can be estimated simultaneously. By the experiments on some real Raman spectra,this algorithm has a very fast convergence,and can improve the resolving power and correct the relative intensity distortion considerably. |

| Keywords: | Raman spectra blind deconvolution high-order statistic super-exponential algorithm |
