- W4306972435 abstract "• In the premise of the irrelevance between speckles of different wavelengths, the speckles of different wavelengths can be separated from the broadband speckles and then respectively reconstructed. • The proposed method can realize color imaging through scattering media based on mixed spackle pattern separation without prior or reference information. • The proposed method is also applicable when the total light signal is weak or the SNR of the system is low. • The proposed method reduces the limitation of speckle correlation imaging that light sources should be narrow-band. Color imaging of objects hidden behind scattering media is significant to many imaging scenarios. Although various color imaging methods have been proposed, most of them need to get prior or reference information. To avoid this, an imaging method of reconstructing color objects through scattering media is proposed in this paper, which is based on the irrelevance between speckles of different wavelengths and speckle correlation imaging. The speckles of different wavelengths are separated from the detected broadband speckles by the improved FastICA algorithm. Then the separated speckles are respectively reconstructed by the phase retrieval algorithm. This method is also applicable to reconstructing color objects surrounded by scattering media. The proposed method explores a direction for color imaging through scattering media based on spectral unmixing algorithms that separate speckles of different wavelengths from broadband speckles and has the potential value to be further developed to realize multispectral anti-scattering imaging." @default.
