"light-scattering material include clouds and body tissue... calibration-free, reconstruction-free, real-time imaging of static and moving objects with their actual orientation information... only requires simple or low-cost devices, without post-computational reconstruction... passed light from small standardized test object through thin diffusing material. By moving camera in a direction away from diffuser, built 3D image taking slices through the speckles"
