Figure 4. Imaging a hidden time-variant object.

Figure 4

a, Experimental arrangement. The SLM surface is imaged by a lens onto the surface of scattering medium 1 for memory scanning. The energy transmitted through scattering medium 2 is measured by a CMOS camera. Inset: the target and TRAP patterns. a1, Photograph of the target (plotted in absorption to reverse the contrast). a2, Intensity distribution of the TRAP pattern. b, The target’s autocorrelation coefficient measured as a function of incident angle. c, The reconstructed object plotted in normalized absorption coefficient. Scale bars, 100 μm.
