The characteristics, including temporal resolution, dynamic range, and time distortion, of our femtosecond streak image tube developed a few years ago have been examined systematically by experiments under different conditions. It can be concluded from the experiments: (1) in order to achieve a temporal resolution of less than 400 fs with acceptable fluctuation the travelling wave deflection system and specially processed photocathode have played an important role, (2) to expand the dynamic range and to stabilize the temporal resolution it is of importance to minimize the noise and to accumulate the signal along the slit, (3) to accomplish above signal accumulation along the slit the time distortion has to be eliminated, which could be realized by using our specially designed optical lens. The aim of this study is to improve the temporal resolution up to 50 - 100 fs by a newly designed femtosecond streak image tube.
