| Abstract: | Using method of integral circuit, the narrow pulse signal of high repetition frequency solid laser was captured. Theory of integral circuit was analysed. Amplification circuit for period narrow pulse signal was designed. Origin and treating of measuring error were discussed. Taking W77E58 as CPU, choosing FT245BM for USB interface circuit, fast acquisition and transmission of narrow pulse signal were realized. Problem of multipath real-time acquisition and transmission to host are well settled. Approving effect is achieved. |
