The measuring device is structured by including a He-Ne laser; a beam expander, a soft aperture slot and a off-axis parabolic mirror to be measured are arranged in turn along the direction of the emergent laser beam direction of the He-Ne laser; a standard cross hair and a micro objective are arranged in turn on the direction of the reflected beam of the off-axis parabolic mirror; the micro objective is arranged on the focus of the off-axis parabolic mirror; the focus is imaged on an area array CCD; the output end of the area array CCD is connected with a computer; the off-axis parabolic mirror is fixed on a five-dimensional electric adjusting frame.

Both the offset and tilted fedcoupling-slot array between the curved guide and sectoral guides and longitudinal radiating-slot array on sectoral guide are analyzed by moment method, taking into account of the effects of finite wall thickness and mutual coupling between the slots, employing the acceleration algorithms to accelerate the summation of slowly convergent series of the self-admittance of the waveguide-slot aperture, and introducing the surface Fock functions to simplify the computation of the self-and mutual coupling of the slots on the surface of cylinder.
