Phase-shifted fiber Bragg grating (PS-FBG) is a special type of Bragg grating that has attracted extensive attention due to its narrow transmission window and excellent sensing performance. This manuscript aims to discuss the PS-FBG with special sensing characteristics and explore the influence of different inscription technologies on the sensing characteristics of PS-FBG by comparing existing inscription methods. The sensing characteristics, advantages, and disadvantages of PS-FBG with different structures are analyzed.
