| Popis: | Theoretical modeling is performed for a liquid crystal (LC) lens that uses a combination of two dielectric lenses and voltage dividing principle to shape the electric field in space. Electric field, LC reorientation, and optical phase retardation profiles are obtained by numerical simulations. The obtained results are compared with experimental ones, and good agreement is obtained validating the proposed two-dimensional model that uses a limited number of dielectric and geometrical control parameters for this type of lens. |
