Abstract ：
光在透过散射介质后发生散射现象，在成像系统焦平面形成无序的随机散斑图像，因此人们无法直接观测到隐藏在散射介质后的目标的图像信息与光谱信息。利用基于光学记忆效应的散斑相关成像技术，可以实现透过散射介质的目标重建，但当前研究主要针对单波段照明条件下的图像信息恢复，而目标的光谱信息在成像过程中易丢失。提出采用快照式微滤光片阵列多光谱探测器进行多光谱散射成像的方案，通过实验得到宽谱氙灯光源照明条件下的穿透散射介质成像结果。提出了基于光学记忆效应的穿透散射介质目标多光谱信息重构方法，实现了对隐藏在散射介质之后的目标多光谱信息的探测成像。针对多光谱探测器所造成的成像质量差的问题，提出了利用自相关预处理方法...

Abstract ：
Light passing through scattering medium will be scattered and result in a random speckle pattern on the focal plane of an imaging system. So we cannot directly observe the spatial and multi-spectral information of an object behind the scattering medium. Optical memory effect based speckle correlation imaging can realize the reconstruction of the object passing through the scattering medium. However, the previous research mainly focuses on the reconstruction of images at a single wavelength, and the spectral information of targets is easily dropped during the imaging process. In this paper, a multi-spectral scattering imaging method using snapshot micro-filter array multi-spectral detectors is proposed, and the imaging results of objects passing through the scattering medium under the wide-spectrum xenon light source illumination are obtained experimentally. A method of multi-spectral information reconstruction for objects passing through the scattering medium based on optical memory effect is proposed, and the detection imaging of multispectral information hidden behind the scattering medium is realized. Since the multi-spectral detectors provide low imaging quality, an image pre-processing method is proposed based on the autocorrelation to improve multispectral imaging quality of penetrating scattering media. © 2022, Chinese Lasers Press.
