| Research Abstract |
The signal obtained in the phase-scrambling Fourier transform (PSFT) imaging technique can be transformed to the signal described by the Fresnel transform of the objects and therefore pseudo-parallel imaging is feasible. In this study, the improvementsin image quality with such pseudo-parallel imaging were examined and demonstrated. Experiments showed that the image quality was improved and that images almost entirelyfree of aliasing artifacts could be obtained.
