چکیده
|
An intensity-based mach-zehnder interferometric fiber optic sensor using multimode–single-mode–multimode configuration is developed to measure methyl orange concentration in water. the transmission spectrum of the sensor is monitored at 460 nm while subjected to different concentrations of methyl orange (mo) solutions. the transmitted light intensity percent is proportional to the methyl orange concentration. this sensor shows a sensitivity of -37.2 and -37.9 dbm/ppm for the measurement of mo concentration in di and tehran tap water, respectively. this sensor offers easy fabrication, fast response, online monitoring, and proper linear response at low concentrations beside other advantages of fiber optic sensors.

Abstract
|
An intensity-based Mach-Zehnder interferometric fiber optic sensor using multimode–single-mode–multimode configuration is developed to measure methyl orange concentration in water. The transmission spectrum of the sensor is monitored at 460 nm while subjected to different concentrations of methyl orange (MO) solutions. The transmitted light intensity percent is proportional to the methyl orange concentration. This sensor shows a sensitivity of -37.2 and -37.9 dBm/ppm for the measurement of MO concentration in DI and Tehran tap water, respectively. This sensor offers easy fabrication, fast response, online monitoring, and proper linear response at low concentrations beside other advantages of fiber optic sensors.
