Development of Optical Fiber Test Bench for Intensity-Modulated Optical Fiber Sensors

Intensity-Modulated optical fiber sensors are popular because of their simple construction and inexpensiveness. The major problem while the development of an intensity-modulated fiber sensor is to have a test bench that can test such sensors with different light sources. The stability of the intensity of LED sources is a major challenge. The paper describes the microcontroller-based test bench which takes care of the intensity stability of the light source. This test bench also takes care of stray radiations. The standardization of the optical fiber sensor is a big challenge and this effort is a small step towards it.
