We propose to size a light field display based on a standard smartphone screen to which is associated a simple array of custom-made microlenses, aimed at evaluating the refractive error of a user's eye. We show theoretically that, to that end, we can display some content with a constant angular resolution over a wide range of refractive errors, i.e.

We study the far-field reflected diffraction pattern of an index discontinuity in a thin one-dimensional slab illuminated by a plane wave and show that a time-saving modeling technique based on plane wave expansion approaches fairly well the Maxwell-based rigorous models. This method is simple to implement, and it furthermore allows a good understanding of the optical phenomena involved in the propagation of light through the slab.

In that case, the diffraction orders show shapes that have not been identified in earlier studies and that are quite sensitive to the pixel filling ratio as well as to decentering.
