Scatter Ptychography
Qian Huang, Zhipeng Dong, Yuzuru Takashima, Timothy J. Schulz, David J. Brady
Coherent illumination reflected by a remote target may be secondarily scattered by intermediate objects or materials. Here we show that phase retrieval on remotely observed images of such scattered fields enables imaging of the illuminated object at resolution proportional to λRₛ/Aₛ, where Rₛ is the range between the scatterer and the target and Aₛ is the diameter of the observed scatter. This resolution may exceed the resolution of directly viewing the target by the factor R_cAₛ/RₛA_c, where R_c is the range between the observer and the target and A_c is the observing aperture. Here we use this technique to demonstrate ≈32× resolution improvement relative to direct imaging.
