Bifurcated Optical Fiber Sensor for Weight Measurement System

Abstract

Analyze some of the basic principles involved in the design of optical fiber based displacement sensor and to apply it to design a weight measurement system. Bifurcated optical fiber sensors can have many applications. Having high sensitivity to short distances, bifurcated optical fiber (Y-sensor) is well suited not only for control applications as position sensors, but also for gauging and surface assessment. In addition, they can be utilized as non contact pressure sensors if used in conjunction with reflective diaphragms moving in response to pressure. Y-sensor can also be applied as temperature transducer if used in conjunction with deformable bimetal sensors.
