“…Currently, it is difficult to capture or detect all these features for sensors using non-contact technology. At present, there are many sensors, such as temperature [1], displacement [2,3], liquid [4], humidity [5], strain [6], angle [7], and sensor deformation [8]. The rotation sensor plays a vital role in a wide range of technical solutions and becomes the main research and development object [9].…”

The sensor design is quite complicated and robust in the current era, requiring a different signal processing technique to process the data and increase sensor cost. At the same time, demand leads to a simple structure and cost-effectiveness. This paper proposed a rotation sensor using polymethyl methacrylate (PMMA) fiber, and the dynamic has been achieved. The method of design structure is based on the intensity variation. In this structure, two PMMA fibers are taken and twisted. The LED light source is coupled with the first fiber, and light propagates in the second fiber is based on the coupling of macro-bend loss. After twisting, both fibers are kept in a macro-bend shape and fixed on the linear translation stage. The translation stage is drafted via a stepper motor. The macro-bending radius variation causes the macro-bend loss in the first fiber, and the loss is being coupled in the second fiber. The change in the macro-bend radius corresponds to the rotation of the stepper motor. In the experiment, a clock and anti-clockwise cycle are carried out. The 2°\sec, 3°\sec, 5°\sec, and 10°\sec rotational speed are conducted to the sensor's dynamic response. The proposed design is cost-effective and straightforward toward the dynamic rotation sensor.

“…In these applications, it is difficult to use traditional measurement sensors based on the capacitive or the magnetic effect because precision, accuracy cannot be compromised [10] To date, several contact and non-contact types sensors have been designed for the measurement of physical quantities such as pressure [11], displacement [12], angle [13], temperature [14], level monitoring [15], and strain [16]. Most of the reported angle sensor's working principle is based on different mechanisms such as capacitive [17][18][19][20], magnetic [21], and optical-fiber [22,23]. Furthermore, Ellin and Dolsak [24] had designed rotary encoders for the different rotary motion applications.…”

The developed angle sensors are usually used for either clockwise or an anti-clockwise direction. Here, we present a relatively new setup of two angle sensors (1-D and 2-D) for independent and simultaneous clock and anti-clockwise rotation measurements. The proposed sensor is based on the twisted macro-bend coupling method (TMBC), in which two fibers are twisted and bent. The two-angle sensors are presented in which sensor-1 consists of a single twisted bend and sensor-2 contain two twisted bends on a single transmitting fiber. The angle measurement relies on the coupling of macro-bend loss. The stepper motor is used to drag the twisted fiber, resulting in a change in the bending radius that increases or decreases the macro-bend loss. A novel cascading method is introduced in the TMBC method for the sensor-2 and, two stepper motors are used in the second experiment. To prove the practicality, several test scenarios are conducted for both sensor configurations. The experimental results show that sensor-1 can measure angle ±180º, whereas the full clock and anti-clockwise cycle are achieved through sensor-2, having a measurement range is ±360º. Therefore, the proposed sensor can be a potential means for accurate angle measurement in industrial applications.
