本文介绍了性能稳定可靠、精度高、成本低的普适光谱调制传感器。使用这种传感器的光学测量装置不受光源强度变化的影响,也不受由于光纤弯曲和光纤连接器损失所引起的透射率变化的影响。该光谱调制传感器系统可探测多种物理参数,如压力、温度、气体密度和多种化学物质,文章中将加以介绍。 This article describes the performance of stable, reliable, high precision, low cost universal spectral modulation sensor. Optical measuring devices using such sensors are not affected by changes in light source intensity nor by the change in transmittance due to fiber bending and fiber optic connector loss. The spectral modulation sensor system can detect a variety of physical parameters, such as pressure, temperature, gas density and a variety of chemical substances, the article will be introduced.
