The technology using Optical Transition Radiation (OTR)which is a main method for measuring the electron beam of high energy and high current has been developed for the past ten years. OTR characterized by the ultra-fast response, high resolution and capability of measuring both spatial and angular profiles of an electron beam. It also can measure the beam energy and divergence. A time-resolved measurement results of an electron beam produced by Linear Induction Accelerator ( LIA ) can provide much more detail information so that many problems about the beam transmission can be known well. Such a time-resolved measurement system has been developed recently in our lab and put into operation. It provides an on-line beam diagnostic method for a 18.5MeV, 2kA, 90ns(FWHM) electron pulse by Dragon I[1]. The beam emittance and its variation during the 90ns pulse are obtained in 10ns time interval. The time-resolved results of about 2200π.mm.mrad have been obtained from Dragon I.
