| 摘 要： | In this paper, a low-cost measurement approach with bi-beam was presented, which can be used for real-time detection and online analysis of solution refractive index, based on systematical analysis and experiments of conventional detection methods on surface plasmon resonance sensor. This novel method was analyzed theoretically and based on it a sensor system set was established. The factors that affect the sensor's sensitivity and working range were discussed. The angular adjustment setup was simplified, errors produced by movable components were avoided and the maneuverability was enhanced with this new method. The noiseproof feature and stability of the sensor system were greatly improved as well.

| Abstract: | In this paper, a low-cost measurement approach with bi-beam was presented, which can be used for real-time detection and online
analysis of solution refractive index, based on systematical analysis and experiments of conventional detection methods on
surface plasmon resonance sensor. This novel method was analyzed theoretically and based on it a sensor system set was established.
The factors that affect the sensor’s sensitivity and working range were discussed. The angular adjustment setup was simplified,
errors produced by movable components were avoided and the maneuverability was enhanced with this new method. The noiseproof
feature and stability of the sensor system were greatly improved as well.
