Modeling and Temperature Drift Compensation Method for Surface Plasmon Resonance-Based Sensors

This paper reports a model for surface plasmon resonance biosensors that includes the influence of all system variables and known disturbances and noise. The model allows to individually analyze each component and the entire system as well. The influence of temperature and wavelength of the incident light alike have been explored, both quantities are intertwined. This later variable proved to be more relevant. Two control configurations were identified to adjust for the wavelength rather output power, as done traditionally. This approach is more energy efficient and allows implementation into battery operated hand held mobile phone-based sensors.
