Refractive index neffIt changes, by the equivalent refractive index n for changing the refractive index modulation layer 23 that material is liquid crystaleff, so that light is logical
Cross the equivalent optical path n for the refractive index modulation layer 23 that material is liquid crystaleff d3Change (neff: material is the refractive index tune of liquid crystal
The equivalent refractive index of preparative layer 23, d3: material is the thickness of the refractive index modulation layer 23 of liquid crystal), it is public according to imaging according to convex lens
FormulaIt is found that the focal length f of convex lens is constant, object distance u (n1d1+neffd3+n2d2, n1: the refractive index of the first transparent substrate,
d1: the thickness of the first transparent substrate, n2: the refractive index of the second transparent substrate, d2: the thickness of the second transparent substrate) it changes
(u < f) is realized and is imaged at the different depth of field so that image distance v changes.By to the refractive index at 31 position of different pixels island
Modulating layer 23 applies different voltages, so that convex lens 11 at different locations has different object distance u, therefore at different location
