Notes:

This slide shows a photograph of our liquid crystal device when it is programmed to form a simple 1-diopter lens to correct myopia, or "short-sighted" vision. Again we are using a dark color code to represent relative retardance and a bright color code to represent relative advancement of the wavefront. This photo also shows the trace of electrodes used to address each cell independently. In normal use of this device an aperture would mask off these electrodes, leaving just the circular array of hexagonal cells as the optically active part of the device.

Although we use light and dark to represent the relative refractive index of each cell, the device itself is completely transparent, as shown on the next slide.
