Description

【図面の簡単な説明】[Brief explanation of drawings]

第１図は弾性体の材料で作られたレンズの端部に外力で

この場合は引張力）、３・・・弾性体材料で作られたケ
ース、４・・・液体又は気体、５・・・圧力変化機構。Figure 1 shows how the lens ζ distance is changed by applying an external force such as tension or compression to the end of a lens made of an elastic material, and Figure 2 shows the case and interior of the elastic material. This figure shows how the focal length of a lens made of liquid or gas is adjusted by changing the curvature by changing the internal pressure. 1... Lens made of elastic material, 2... External force (
In this case, tensile force), 3...A case made of an elastic material, 4...Liquid or gas, 5...Pressure change mechanism.
