     "The scan model is one of the core components that defines a ptychography experiment, it creates different data structures such as [Views](https://ptycho.github.io/ptypy/rst/ptypy.core.html#ptypy.core.classes.View), [Containers](https://ptycho.github.io/ptypy/rst/ptypy.core.html#ptypy.core.classes.Container) and [Storages](https://ptycho.github.io/ptypy/rst/ptypy.core.html#ptypy.core.classes.Storage). It also creates the [PODs](https://ptycho.github.io/ptypy/rst/ptypy.core.html#ptypy.core.classes.POD) which link the containers (and views) of probe, object, exit wave and diffraction data. This figure provides an overview of how PtyPy models an ptychographic experiment\n",

     "**The PtyPy model in a nutshell:** (a) Experimental sketch of a ptychographic experiment with optics focused on a sample and diffraction measured by a detector. (b) For each experimental view, PtyPy's **pod** captures all relevant properties from probe/object to exit wave, forward proejctor and diffraction data. (c) Example images for single view. (d) Diagram of the network of pods, each connected to a data view, a probe an object view and an exit wave. (e) Each pod has a container for the probe, object and diffraction - these containers are themselves connected underlying storages."
