Abstract
In this paper, crystalline optical fibers were used as a sensor for sensing the zinc ion concentration using the image processing technique. The image of the laser spot transmitted through the optical fiber crystal sensor for each concentration of zinc ion solution. The sensor was made by welding a piece of LMA-10 crystal optical fiber from both ends of a single-mode optical fiber to obtain an SM-PCF-SM type sensor. And it is possible to distinguish between one concentration and another by studying the change of the images obtained as a result of changing the concentration of the zinc ion. The sensitivity of the manufactured sensor was about 73.47%.
Highlights
Image processing was used with fiber to reduce the cost of work and increase the speed of obtaining results. The results of the image were translated into an intensity curve and drawn in the form of a force curve. The sensitivity of the sensor was obtained and found that it was equal to 73.47%.
