Misaligned Reflective Tomography Image Reconstruction Algorithm Based on Phase Retrieval
We study the theory of laser reflective tomography technology based on computed tomography. In practice, due to the movement of the target and the vibration of detection platform, there are the shifts between the reflection projections of non-cooperated target at different angles and the target rotation center, which is projection-misalignment and causes the distortion and constructed defects of reconstructed image from projections. We use the error-reduction and hybrid in-out algorithm to recover the phases of reflective tomography reconstructed images with misaligns. The simulation verifies the feasibility of the algorithm under the angles of oversampling, full projection, and sparse projection of projection angles.
