摘要

计算光谱仪在现场测量的实时检测方面潜力巨大。重构算法发挥着关键作用。传统的重构算法虽然对计算资源的要求较低,并能实现实时测量,但在实现高重构精度方面往往面临挑战。基于深度学习的方法可提供高精度重建,但需要更多计算资源,且缺乏可解释性。在这项工作中,我们提出了一种端到端可解释的展开网络,它将 ADMM 算法的迭代过程转化为网络层,并自主学习稀疏基矩阵,确保每个网络参数都有明确的物理含义。该算法的性能在两个合成频谱数据集和一个测量频谱数据集上得到了验证。结果表明,我们的方法不仅确保了高重建精度和鲁棒性,还减少了计算资源。总之,该算法避免了神经网络的黑箱特性,并涉及物理模型,在实现计算光谱学的高精度实时测量方面具有巨大潜力。

Fast spectrum reconstruction based-on interpretable network with physical model involved
Computational spectrometers has a great potential for real-time detection in site measurements. Reconstruction algorithms play a pivotal role. Traditional reconstruction algorithms, while demanding low computational resources and enabling real-time measurements, often face challenges in achieving high reconstruction accuracy. Deep learning-based methods offer high-precision reconstruction but require more computational resources and lack interpretability. In this work, we propose an end-to-end interpretable unfolding network that translates the iterative process of the ADMM algorithm into a network layer and autonomously learns sparse basis matrices, ensuring that each network parameter has a clear physical meaning. The performance of this algorithm was validated on two synthetic spectrum datasets and a measured spectrum dataset. The results demonstrate that our method not only ensures high reconstruction accuracy and robustness but also reduces the computational resources. Collectively, this algorithm avoids the black-box characteristics of neural networks and is with physical model involved, which has significant potential to enable high-precision real-time measurements in computational spectroscopy.
