Scattered light imaging beyond the memory effect using the dynamic properties of thick turbid media
Fig. 1. Conceptual illustration of scattering state traversal. (a) A scattering state corresponds to a portion of the spatial information. The reconstruction range of the state is restricted by the ME range. (b) Another scattering state and (c) ensemble scattering states that traverse different scattering regions, enabling the retrieval of information beyond the ME range.
Fig. 2. Imaging through a dynamic diffuser approaching ergodicity. (a) Schematic of the experimental setup. The thin scattering medium swings as a pendulum. (b) ePSF, (c) eI, and (d) the reconstructed object at different superposition times
Fig. 3. Image reconstruction through a dynamic medium. (a) Experimental setup for the time-variant thick turbid medium. (b) Reconstructed intensity at different horizontal positions, showing the vignetting characteristic curve of our experimental setup. (c) Original, (d) scattered, and (e) reconstructed images of the round hole at various angles.
Fig. 4. Full range simultaneous reconstruction. (a) Raw object and (b) reconstructed object and the corresponding ePSFs at different superposition times
Fig. 5. Reconstruction of unknown targets with prior information. (a) Reference object, a letter “H,” (b) ensemble speckle of the reference object, (c) ensemble speckle of the reference and unknown objects, and (d) reconstruction of the unknown objects, the letter “G” and “F.”
