Abstract
This work relates to a geometric-phase metasurface combined with a fluidic circuit for tuning the properties of the metasurface (especially its diffraction efficiency). We consider two aspects of particular interest: A) Dynamic on-demand diffractive optics (operating in transmission), both as optical elements for altering incident light, and as sensors of the refractive index of a fluid; and B) Transparent, reflective displays. Here the display itself is transmissive, but operates in reflection. One application of dynamic on-demand diffractive optics is to replace the lens array often needed in light field displays.
