引言 幅度传感器基于各种换能机理。凡产生正比于外加信号的光强度变化的任何换能技术都可归为这类传感器。幅度传感器是与光纤干涉仪或相敏装置性质不同的一类简单的传感器。尽管偏振传感器取决于检测光相移,为完整起见,这里也把这种传感器归纳在内。 Introduction Amplitude sensors are based on a variety of transduction mechanisms. Any transducer that produces a change in light intensity that is proportional to the applied signal can be classified as such a sensor. Amplitude sensor and optical fiber interferometer or phase sensitive device of a different type of simple sensor. Although the polarization sensor depends on the phase shift of the detection light, for completeness, this sensor is also included here.
