Abstract: To study the application and development of stretched wire technology in accelerator alignment and survey, the principle of stretched wire technology is summarized firstly, then the development history of stretched wire alignment method in accelerator is reviewed, and the latest development trend of stretched wire alignment method is introduced. Finally, the advantages and disadvantages of various alignment methods and their suitable environments are discussed, and the development differences between domestic and foreign alignment methods are compared. The development direction of the stretched wire alignment method is pointed out, and the direction of the accelerator alignment and survey is given.
