Title: MILLIMETER WAVE HOLOGRAPHIC IMAGING DEVICE CAPABLE OF SCANNING OPPOSITE CYLINDRICAL SURFACES
Abstract:
A millimeter wave holographic imaging device capable of executing opposite cylindrical surfaces scanning. The millimeter wave holographic imaging device comprises: a first and a second arc-shaped sliding rail supports (40, 50); and upper arc-shaped rails (41, 51) disposed at the tops of the arc-shaped sliding rail supports (40, 50) respectively, and lower arc-shaped rails (41’, 51’) parallel to the upper arc-shaped rails and disposed at the bottoms of the arc-shaped sliding rail supports (40, 50) respectively. Arc-shaped paths, respectively defined by the arc-shaped sliding rails of the first and second upper arc-shaped rails (41, 51) positioned at the upper portion constitute a pair of non-concentric opposite arc-shaped paths. A first and second vertical millimeter wave transceiver devices (60, 60’) are disposed between the upper arc-shaped rails (41, 51) and the lower arc-shaped rails (41’, 51’) in a vertical direction and can move along the arc-shaped sliding rails of the upper arc-shaped rails (41, 51) and the lower arc-shaped rails (41',51'). A wheel fork (70) is further provided to drive the first and second vertical millimeter wave transceiver devices (60, 60’) to move along the arc-shaped sliding rails respectively.
