Design of quasi-optical system for near-field passive millimeter wave imaging
摘要
Abstract
Near‐field passive millimeter wave imaging is one kind of the most promising technologies for the safety inspection of concealed weapons .A quasi‐optical system of near‐field millimeter wave imaging is designed based on geometrical optics and Gaussian beam method .The system uses a pair of planar mirrors to scan the target plane along the vertical and the horizontal direction ,respectively .A double refraction lens is used to realize focus imaging of millimeter wave .Meanwhile ,it adopts a bolometer working at 3 mm wavelength as a detector to receive millime‐ter wave radiations .The distance between the target plane and the system is less than 1 .5 m ,the imaging area is 1 .2 m × 0 .6 m and the spatial resolution is 30 mm .Theoretical analysis and simulation results show that the system has good imaging quality and meets the design index .It can be applied for public inspection in particular for non‐con‐tact safety inspection ,and adapts to the development of near‐field passive millimeter wave imaging system which features light weight ,compact volume and high imaging quality .关键词
