提出了一种新颖的基于荧光的光学传感器的通用结构。染料掺杂的溶胶-凝胶膜发射的被测量敏感的荧光被有效地捕获，并被引导到平面波导中。荧光发射的各向异性导致激发光和荧光发射的角度分离，这可能消除对滤光器的需要。
A novel generic configuration for fluorescence-based optical sensors is presented. The measurand-sensitive fluorescence emitted from a dye-doped sol-gel film is captured efficiently and guided along a planar waveguide. The anisotropy of the fluorescence emission results in the angular separation of the excitation light and fluorescence emission which may eliminate the need for optical filters.
