Detected intensity reconstruction in output (CCD2) plane.
In (a), the target was included in the beam path, It was illuminated (in reverse) by five different speckle patterns (generated by random SLM patterns) and the average result is shown. In (b)–(d), the target was removed from the beam path (flipped down), in order to generate a reconstruction by DOPC alone. Considering the individual cases: (b) No SLM control, resulting in turbid sample illumination with a plane wave; (c) Optimized SLM control in the absence of “fine-tuning”; (d) Optimized, fine-tuned SLM control. Scale: each element-5 bar has (long-dimension) length 1.57 mm. Consistent but arbitrary intensity units are utilized in the images.
