Universal Spectral Modulation Sensors

Abstract: A universal spectral modulation sensor with low cost, stable, reliable and accurate performances is presented. The optical measuring device using a universal spectral modulation sensor is immune to change the intensities of the light source and light transmission due to optical fiber bending and optical fiber connector loss. The application of spectral modulation sensor system are presented that is to detect and measure various physical parameters such as pressure, temperature, gas density, and various chemical species.

Keywords: Spectral Modulation Sensor, Optically Resonant Structure, Chemical Species Sensor, Gas Density Sensor, pH Sensor, Pressure Sensor, Temperature Sensor.
