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%.

In this paper, the Oil leakage sensor utilized photonics crystal fiber interferometer (PCFI) is proposed and experimentally investigated. The principle of operation of this sensor is detected the gas emission from pipe. This sensor is operate in transmission mode which designed by splicing the LAM-10 PCF with single mode fiber (SM) with two side. To increase the sensitivity of this sensor the splice region is coated by special polymer doping by nano sliver silver particles to increase the sensitivity. The experimental result s shows the sensitivity of fabricated sensor is high, and the response time is very short reach to 2min the max sensitivity is equal to (62 Co./sec ). Due to the low fiber loss, the sensing range can be as high as 1 km.
