LIQUID LENS MAXIMIZING THE ELASTIC STRAIN ENERGY |
| 摘要 |
Liquid lens (100) including two liquids (104, 105) being adjacent to each other in a container (101, 102, 103) with a flexible member (106) interposed between them wherein at least a part of the flexible member (106) functions as refractive surface and characterized in that the elastic strain energy per unit area Y [N/m] of the flexible member satisfies the inequality γ≧5.16×105×Δρ×α−1×3.4, where Δρ [kg/m 3] is the density difference between the two liquids arranged adjacent to the flexible member; α [λ] is the surface accuracy of the refractive surface; and φ [m] is the inner diameter of the liquid lens. |

1. A liquid lens comprising two or more liquids arranged adjacent to each other in a container for containing the liquids with a flexible member interposed between them, at least a part of the flexible member functioning as refractive surface;
the elastic strain energy per unit area γ[N/m] of the flexible member satisfying the requirement of formula (1) represented below;
γ≧5.16×105×Δρ×α−1×φ3.4 formula (1),where
Δρ[kg/m3] is the density difference between the two liquids arranged adjacent to the flexible member; α[λ] is the surface accuracy of the refractive surface; and φ[m] is the inner diameter of the liquid lens. |
