Abstract
Based on the optical memory effect, many speckle-correlation methods have been proposed for imaging through scattering media. However, most of these methods directly take the laser with a rotating diffuser as a pseudo-thermal source without discussing its physical basis. To explore the effect of different optical coherence on object reconstruction, the principle that rotating diffuser can weaken the coherence is discussed and validated by experiments in this paper. Specifically, the degree of coherence is changed by controlling both the speed of the diffuser and the size of the illumination spot. And the speckle patterns collected under these conditions are reconstructed by Speckle-Correlation Algorithms (SCA). Through theoretical derivation and experiments, it is well demonstrated that the low coherence facilitates the recovery of the object. In addition, it is found that the stacked ground glass moving along a single direction can replace the rotating diffuser to achieve light source decoherence. The effect of different optical coherence on scattering imaging is explored in this paper, which provides a theoretical basis for selecting the light source in speckle-correlation imaging.
