Absorption luminosity detecting sensor based on micro-fluid control channel full-reflection integration light waveguide

The invention discloses an absorption luminosity detecting sensor based on micro-fluid control channel full-reflection integration light waveguide, relating to a sensor technology. An optical full-reflection thin film can be selectively prepared in a micro-fluid control channel by using a chemical deposition method, so that the entire integration of a transmission channel and a detection channel of light in micro-fluid control optical detection can be realized. Light with a special wavelength enters an absorption pool through incident light waveguide, spreads inside the absorption pool along liquid core light waveguide and is partially absorbed by a solution to be detected, and finally enters a silicon light diode through emergent light waveguide, thus finishing the luminosity detection. In-situ preparation of the light waveguide on the micro-fluid control chip can be realized through the sensor provided by the invention, so that the integration and the reliability of a absorption luminosity method detection chip based on the micro-fluid control technology can be greatly improved. The absorption luminosity detecting sensor has very important reference meanings on the development of a fluorescence method and a chemiluminiscence method based on micro-fluid control optical detection.
