Abstract: |
The invention relates to a full optical fiber instant passing wave biology sensor technology to realize biological detection by using laser to excite the biology material to emitting. The feature is that the laser transferring and fluorescence receiving path of the sensor contains an optical fiber probe, a single and multiple optical fiber coupler. The laser from the laser emitting device would send to the end of the single-mode optical fiber, and the other end coupling to multimode fiber. One end of the multimode fiber connects to fiber probe, and the other end locating in the light incidence end of fluorescence collecting and data processing device. The invention could decrease the consumption, improve coupling efficiency and decrease optical discrete element and simplify instrument structure. |
