Abstract

Imaging through dynamic scattering media has very important applications in many fields such as autonomous driving and drones. In this article, we propose an imaging method based on combined modulation of dynamic scattering medium and spatial light modulator. This method is based on the compressed sensing (CS) imaging model, and uses the combined modulation as the modulation mechanism to achieve the target reconstruction. The results of optical experiments show that the combined modulation method can successfully reconstruct the target image. It is also suitable for dynamic scattering media with large changes in concentration. Moreover, the algorithm comparison experiment results show that compared with the orthogonal matching pursuit (OMP) algorithm, the total variation algorithm can improve the quality of the image.
