| 摘 要： | 基于角度扫描的表面等离子体共振(SPR)传感器,装置简单、容易实现、性能稳定,其测量精度由角度测量精度决定。提出了一种基于激光自混合干涉效应的零角位置自动校准方法,主要用于角度扫描的表面等离子体共振传感器零角位置的自动校准。这种方法克服了人眼观察时用自准直法难以判断两光点是否完全重合的缺点,其精度可满足实验要求。

| Abstract: | Surface plasma resonance(SPR)sensor is based on the angle scanning,the device is simple and easy to implement,stable performance,and its measuring accuracy is decided by precision of angle measurement.A automatic calibration method at zero angle position is presented based on laser self-mixing interference effects.The method is used in the surface plasma resonance sensor of angle scanning.It can overcome shortcomings that collimation of eye observation is difficult to judge whether the two-point entirely coincidence,and meet the precision that experimental requests. |
