Orthogonal Translation Computed Laminography
Parallel translation computed laminography (CT) has higher imaging resolution in the direction of scanning and lower spatial resolution in the direction perpendicular to the scanning direction. We propose an orthogonal translation CL (OTCL) method to perform line scanning and realize high resolution imaging for objects to be detected in two orthogonal directions. A geometric model of the OTCL is established, the scanning motion is analyzed, the experimental system is established, and simultaneous iterations reconstruction (SIRT) algorithm is used to reconstruct CL images. Simulation and experimental results show that the OTCL method is feasible and can be used in the nondestructive testing of flat plate parts.
