“…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.

“…On the other hand, wavelength modulation can be very costly since it needs optical spectrum analyzer (OSA) and fiber Bragg grating (FBG) for data acquisition and physical parameter detection, respectively [15]. Most of FODS employed intensity modulation technique [15][16][17][18][19][20][21], which is the simplest method to obtain high resolution measurement. The intensity-modulated based sensors (IBS) offer high precision while also having high bandwidth and less expensive components [22].…”

In this paper, a low-cost fiber optic displacement sensor (FODS) using a bundle of plastic optical fiber (POF) as a probe is developed and presented. The sensor consists of a high power light emitting diode (LED) as light source, a probe with multiple receiving plastic optical fiber and a photodiode detector. The sensor is characterized at millimeter distance and the sensor output is analyzed from 0 mm to 13 mm displacement. The sensitivity of the sensor is found to be 5.38 mV/mm over 2.6 mm sensing range. The sensor is very useful for close distance target since it is highly sensitive at the front slope. The low development cost, high degree of sensitivity and simplicity of the design make it suitable for wide range of industrial applications.

“…Optical fiber sensors have been widely used in measuring various physical, chemical, and even biological parameters, as they are compact, responsive, sensitive, stable and resistant to electromagnetic interference [1][2]. They have also been recommended for applications in areas such as structural monitoring of buildings [3], estimation of metal surface roughness [4], vibration tests [5], determination of the thickness of a transparent plate [6], etc.…”

Highlights  A load sensor uses a single-mode-multimode-single-mode (SMS) fiber structure.  The SMS structure is sandwiched between two CR-39 plastic polymer plates.  A larger effective transverse strain can be achieved when the distance between the stage and the edge of the multimode fiber is larger.  The SMS device is suitable for sensing a small load or transverse strain with a reasonably high sensitivity.
