技術說明

本發明係關於一種可調變聚焦元件及其系統，其中該可調變聚焦元件係藉由於一透光基板的內部形成一封閉式流道而製成，且該封閉式流道係與該透光基板共同構成類似菲涅爾透鏡結構；並且，該可調變聚焦裝置係由該可調變聚焦元件與一流體注入與抽出裝置所構成。於本發明中，當光線照射該基板之一側時，該光線會受到該封閉式流道之結構的影響而被聚焦至基板另一側的一特定焦距之上，達到聚焦光線之效果；此外，使用者可透過該封閉式流道之流道口將具有特定折射率的流體注入於該封閉式流道之中，進以藉此不同流體之不同折射率而達到不聚焦或調整焦距之目的。 The present invention relates to a focus-adjustable device and a system thereof. The focus-adjustable device is fabricated by forming a closed flow channel in the internal of a transparent substrate, so as to make the transparent substrate and the closed flow channel together form a specific lens structure similar to the Fresnel lens. Besides, the focus-adjustable system is constituted by the focus-adjustable device and a fluid injecting and pumping device. In the present invention, when a light illuminates on one side of the substrate, the light would be concentrated at a specific focus distancing from the other side of the substrate after being deflected by the specific lens structure. Moreover, a user can inject a fluid having a specific refractive index into the closed flow channel by a flow channel opening, so as to carry out the purpose of adjusting focus, or without focusing the light.
