More Information
Summary:An optical zoom probe is disclosed. The disclosed optical zoom probe comprises: an opening controller controlling an opening where light transmitted from a transmission unit passes; a focus control unit having first and second liquid lenses of which curvatures are independently controlled to control a focal distance to super-proximity and proximity positions and focusing light passing the opening; and a filter unit having a central area enabling the incident light to pass therethrough without a change and having a filter area positioned to surround the central area and provided to expand depth of focus of the light focused to the super-proximity position. 광학 줌 프로브가 개시된다. 개시된 광학 줌 프로브는, 전송부에서 전송된 광이 통과하는 개구를 조절하는 개구 조절기와, 개구를 통과한 광을 포커싱하며 초근접 위치 및 근접 위치로 초점 거리를 조절하도록 곡률이 서로 독립적으로 제어되는 제1 및 제2액체 렌즈를 포함하는 초점 조절 유닛과, 입사되는 광을 변화없이 통과시키는 중심영역과 이 중심영역을 둘러싸도록 위치하며 초근접 위치로 포커싱되는 광의 초점 심도를 확대하도록 마련된 필터 영역을 포함하는 필터부를 포함한다.
