Intensity-modulated surface plasmon resonance (SPR) array sensor based on polarization control was introduced and the impacts of incident angle, gold firm thickness, polarizer angle, wavelength and data processing on its sensitivity and measuring range were analyzed. It was concluded that in an easily controllable measurement range, an appropriate parameter selection can be set and produce high sensitivity with a simple optical and mechanical structure and lower production costs. This scheme can be widely applied to the high-throughput detection of bimolecular interaction analysis, environment monitoring, food safety, pharmaceutical analysis, biomedical engineering and other fields.
