In order to realize the high-resolution reconstruction of static target objects hidden behind the scattering medium and the reconstruction and real-time tracking of dynamic target objects, avoid the unpredictability of pseudo-thermal light sources generated by rotating ground glass and the impact of mechanical vibration on imaging quality, a spatial light modulator is applied to the speckle-related imaging system to generate the pseudo-thermal light field, enabling imaging of static and dynamic targets. The error rate of dynamic target tracking is within a very small range, the minimum can reach 0.38%. In the image reconstruction process, a phase recovery algorithm based on phase retrieval with the swept approximate message passing algorithm is adopted to improve the calculation speed and image robustness. Comparison of the quality of the pseudo-thermal light source and image reconstruction based on phase and amplitude modulation methods is conducted, the result shows that the quality of the pseudo-thermal light source based on phase modulation is better, as well as the corresponding reconstructed image resolution.
