Imaging blood cells through scattering biological tissue using speckle scanning microscopy

We demonstrate imaging of blood cells enclosed in chicken skin tissue using speckle scanning microscopy (SSM). Clear images of multiple cells were obtained with subcellular resolution and good image fidelity, provided that the object dimension was smaller than the maximum scanning range of the speckle pattern. These results point to the potential and the challenges of using SSM technique for biological imaging. (C) 2014 Optical Society of America
