Self-calibration of an optical-based sensor using a total internal reflection (TIR) signature

Self-calibration of an optical-based sensor using a total internal reflection (TIR) signature

A surface plasmon resonance sensor or critical angle sensor has a reflecting surface which is optically flat and exposed to air on one side. Light reflecting from a sensing surface of the sensor which impinges on the reflecting surface at an angle which is less than the critical angle passes into th...

description A surface plasmon resonance sensor or critical angle sensor has a reflecting surface which is optically flat and exposed to air on one side. Light reflecting from a sensing surface of the sensor which impinges on the reflecting surface at an angle which is less than the critical angle passes into the air whereas light which impinges at an angle which is equal to or greater than the critical angle is reflected onto a photodetector. The critical angle reflection from the reflecting surface provides a total internal reflection (TIR) characteristic which is used to calibrate the sensor.
