“…But, it was narrowed by the size of the silicon grating (14 mm x 14 mm). D. Sastikumar et al [15], successfully illustrated and designed and a specific type of displacement fiber optic sensor to sense and determine the thickness of a transparent plate with a limited range between 1-2.5 mm. According to the change of the thickness of the transparent plate, the individual characteristics of this sensor are also varied.…”

Fiber optic sensing technology is one of the fastest growing technologies in the modern day science. Optical fiber sensors draw more and more interests of researchers and application engineers for its exclusive and very valuable characteristics. It is mainly used to sense the physical and chemical properties such as micro-bending, strains, vibrations, accelerations, linear and rotary position, temperatures, pressures, determination of pH, refractive index of liquid solution, pipeline condition monitoring etc. furthermore, fiber optic sensors have a variety of special benefits for example faster response, low-cost fabrication, very light weight, highly sensitive plus non-reactive to electromagnetic interference. Fiber optic sensors can also be classified under various types based on sensing methods and applications. These distinctive and valuable application features facilitate an extensive range of industries such as biomedical, aerospace, structural health monitoring, transportation, oil-pipe condition etc. This paper discusses about the basic working principle of fiber optic sensing technology, various types of fiber optic sensors and their applications and future scope of fiber optic sensors. This paper also discusses about PDMS materials as the coating for fiber optic sensors for improved and enhanced performance. Keywords-Fiber Optic Sensing technology, practical applications of FOS, application of FOS in SHM, PDMS material, compatibility of PDMS and fiber optic sensorsI.

“…It is also plausible that the traditional sensors are replaced with the POFDS to offer significantly enhanced accuracy, quality and the end‐user expense which is prominent nowadays because fiber optic sensors allow calculations of a wide range of variables under conditions in which other sensor devices perform poorly or are actually not ideal 19‐21 . Besides, in various applications, this kind of sensors is shown to be superior 22‐24 …”

A simple plastic optical fiber displacement sensor has been demonstrated as a non‐contact color detection device. The sensitivity of the sensor is 0.0228, 0.1718, 0.1122, 0.106, and 0.1267 mW/mm for black, blue, green, red, and white, respectively. The experimental results prove that as the color changes from dark to bright, the peak output power increases proportionally. The proposed sensor is highly stable and persistent, with additional advantages of practicality of design, high efficiency, comprehensive depth of field, and low cost of production, which could be beneficial for applications in the sensing field.

“…Non-contact measurement methods have been used in the measurement of eddy currents and nuclear radiation, and are exemplified in optical measurement systems based on laser displacement and in measurement systems based on vision systems [5][6][7][8]. In particular, non-contact methods for length measurement based on vision systems have become popular in fisheries [9,10].…”

-This paper introduces a vision-based automatic system (VAMS) for non-contact measurement of morphometric characteristics of flatfish, such as total length (TL), body width (BW), height (H), and weight (W). The H and W are simply measured by a laser displacement and a load cell, respectively. The TL and BW are measured by a proposed morphological image processing algorithm. The proposed algorithm cans measurement, when the tail of flatfish is deformed, and when it is randomly oriented. In the experiment, the average and maximum measurement errors were recorded, and standard deviations and coefficients of variation (CVs) for the measurements were calculated. From those results, when flatfish the TL measurements had an average of 266.844 mm, a standard deviation of 0.351 mm, a CV of 0.131%, and a maximum error of 0.87 mm with straightened flatfish (TL A : 267 mm, BW A : 141 mm), and when flatfish of different sizes were measured, the errors in the TL and BW measurements were both about 0.2 %. Using a single conveyor, the VAMS can process up to 900 fishes per hour. Moreover, it can measure morphometric characteristics of flatfish with a TL of up to 500 mm.
