(English Abstract)
In this paper, we system the system design and numerical analysis of the ultrafast optical delay line using by optical phase modulator. The numerical analysis carried out with 1310nm, lops laser and electro-optic phase modulator. As the results of numerical analysis, we show a scanning rate of 0.5 GHz and a delay range of 19.0ps. Compare with mechanical delay line, the optical delay line has a high scanning speed and a high repetition rate
