LIQUID PRESSURE DRIVING TYPE MULTILAYER LENS WITH VARIABLE FOCAL POINT

A liquid pressure driving multilayer lens comprises a lens part having a first lens chamber and a second lens chamber formed into each hollow to accommodate a liquid and separated from each other by a partition wall, and a driving part forming a first driving chamber and a second driving chamber communicating with a first lens chamber and a second lens chamber respectively by a first driving channel and a second driving channel respectively. As one of the first lens chamber and the second lens chamber is expanded by compression of the driving chamber in communication therewith, the other lens chamber is compressed by the expanded lens chamber. Therefore, an objective of the present invention is to provide the liquid pressure driving multilayer lens with an adjustable focus point. 유체압 구동 다층 렌즈는 각각 중공으로 형성되어 액체를 수용하며 서로로부터 격벽에 의해 분리되는 제1 렌즈 챔버 및 제2 렌즈 챔버가 형성된 렌즈부와, 제1 구동 채널 및 제2 구동 채널 각각에 의해 제1 렌즈 챔버 및 제2 렌즈 챔버와 각각 연통되는 제1 구동 챔버 및 제2 구동 챔버가 형성된 구동부를 포함하며, 제1 렌즈 챔버 및 제2 렌즈 챔버 중 어느 하나가 그와 연통된 구동 챔버의 압축에 의해 팽창됨에 따라, 팽창된 렌즈 챔버에 의해 다른 렌즈 챔버가 압축된다.
