An epic flexible grinding manufacture method is created and various gratings are acknowledged, indicating the capability of the system. Discretionarily formed gratings are consecutively engraved in the fiber by a moving obstruction design made with an Ultra violet (UV) source. This plan takes into account an excellent control and solidness of the grinding shape, which is likewise demonstrated tentatively. As contradicted to most other present manufacture procedures, the proposed strategy offers an all-out command over the grinding parameters by programming, empowering basic execution of new structures. Various types of mistake sources when sewing long gratings are distinguished and researched in regards to effect on the last grinding outcome. Another significant inquiry inside this field is the means by which to describe gratings. Propose another portrayal technique dependent on optical low-intelligence reflectometry (OLCR). Another interferometer configuration takes into account straightforward synchronous location of the reflection reaction from two distinct focuses in the cross examined grinding, so that differential estimations can be performed. The benefit of this is the affectability to clamor brought about by for example warm changes in the system is significantly decreased. A few test gratings have been examined and a generally excellent consent to the normal outcomes is noted. A second portrayal strategy utilizing interferometric identification of the side diffraction from the grinding under test is examined both hypothetically and tentatively.
