This study presents a proposed technique for displacement measurement in linear horizontal motion. The measurement system consists of a lines can sensor with built in illumination system, grating scale and an ultrasonic sensor. Once, the linescan transducer scans the grating scale optically, the displacement of the transducer is measured based on pixel shifting method. Additionally, the role of the ultrasonic sensor is to add the reference position for the linescan transducer and the current position in case of missing the position. The linescan transducer design includes; the illumination source and the division of the grating scale. The accuracy of the measurements is compared to white and infrared lights. After that, the comparison is built based on three scale divisions which are 0.5, 1 and 2 mm. Finally, the accuracy also is compared to different travelling ranges of motion. The displacement measurements of the proposed transducer is evaluated comparatively to Optiv Light Measurement (OLM) device.

“…As a result, optical fiber sensors have been developed for a variety of applications in industry, medicine, defense and research. Some of these applications include gyroscopes for automotive navigation systems [2], strain sensors for smart structures and for the measurement of various physical and electrical parameters like temperature, pressure, liquid level, acceleration, voltage and current in process control applications [2,3]. Optical fiber sensors can be broadly classified on the basis of their operating principle as intensity based or interferometric type.…”

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.
