Multi-rotation computational coherent imaging (MRCI) system has been proposed, in which a custom-built degree calculation method based on Radon transform is specifically designed. However, both coaxial misalignment in rotation and the low robustness of angle calculation limited by sample-diversity degrade the quality of reconstruction. We propose an enhanced MRCI (eMRCI), which combines pre-illumination detection and simulated annealing (SA) compensation. In eMRCI, the pre-illumination mode thoroughly solves the low robustness of angle calculation and simultaneously captures the number of transverse off-axis deviation pixels. For the potential and slight hysteresis error, it is compensated by the SA algorithm. Both simulation and experimental results demonstrate that robust shift correction and angle calculation are achievable. This framework mitigates hardware requirements, and provides a possible new path for position error correction of array-illumination or scanning imaging.
