Passive wakefield devices such as corrugated structures have demontrated great potential for longitudinal phase space control and diagnostics in FEL. In this paper, we will discuss the application of corrugated structures in beam tilt characterization. We show that a tilted beam experience asymmetric kicks when passing through corrugated metal jaws and the asymmetry of streaked profiles are related to the degree of tilt. Practical implementation of beam tilt correction will be discussed.
