Paper Abstract

Fiber-optic sensors are attractive for biomedical applications primarily because of their non- electrical and non-conductive nature. This secures the safety of use and immunity to electromagnetic interference. In addition to these advantages, the optical-fiber level-sensor presented here has a small size, high accuracy, and fast time response. The sensor probe is chemically passive and can be easily sterilized. These features make the sensor attractive for numerous applications in physiology, biochemistry and medicine. The level-sensor presented here is a multipoint discrete optical-fiber device employing an array of small-size liquid- sensitive optical refractometric transducers of new type. The array of such transducers is connected via multi-fiber optical cable to the optoelectronic transmitter-receiver unit of the sensor. It performs an intelligent quasi-continuous level monitoring of a fluid. The sensor accuracy, resolution and level measurement range depend on the array length and the total number of the transducers employed. In case of the most close spacing of the transducers, the sensor level-resolution is better than plus or minus 0.2 mm.
