The primary experiment results of imploding dynamics for single and double planar wire arrays, acquired by optical streak camera, are presented and analyzed. The results show that the interaction of adjacent single wire plasma for single planar wire array is not dus entirely to inelastic collisions, while a part of plasma can move into the center and form precursor plasma across the plane of wire array; the current of outer wire is larger than that of the interior of wire, the time of ablation stage is ~65% of the total imploding time, and only a part of mass participates in the imploding stage.
