Abstract

To solve the contradiction between high delay accuracy and low insertion loss in the development of an optical fiber delay line and to improve the engineering feasibility of the delay line production

a delay line system model based on collimators

a cube-corner prism and a ball screw was proposed. The composition and the basic principle of the optical fiber delay line were introduced. Then

the two key components

optical fiber collimators and cube-corner prism

were designed according to the specific requirements of the project development. After that

an optical aided mechanical structure was designed and assembled. Finally

optical correction and data testing were finished by using an optical fiber laser. Experimental results indicate that the coupling efficiency of the delay line is better than 80.6% within the delay distance from 1 to 9.6 cm meanwhile maintaining higher time delay repeatability and higher accuracy

which satisfies the requirements of radar

communications

electronic warfare for electric systems.
