近幾年來，由於生物科技一日千里，並且搭配成熟的微系統加工技術，使得生物晶片的研究蔚為風潮。其中微流體晶片將實驗室中進行的一連串生化分析，整合至同一晶片中，相較於傳統實驗室，具有反應速度快，樣本及試劑使用量減少等不少優點，因此是未來生物晶片發展的重要方向之一。
而目前在微流體晶片中，所使用的螢光檢測技術，其螢光染料的激發頻譜與放射頻譜通常會有部份重疊在一起，因此在使用濾光片將激發光濾去以增加訊雜比的同時，也會把部份的放射光濾掉，將使得檢測更困難。本文中針對此問題，提出一種新型的檢測架構，把微流道與微光學元件（包含微透鏡及微光柵）作一系統性的整合。
初步以氦氖雷射以及綠光雷射進行測試，使用本生物晶片的架構，並且搭配CCD的檢測方式，可得到一個空間的頻譜訊號分佈。進一步再針對混合光譜的訊號進行分析，期望可以得到原先光譜的混合比例。
