Abstract
In this Letter, we report a setup design to realize high-visibility orthonormalized ghost imaging (GI) with self-correction through dynamic and complex scattering media at low sampling ratios. With the design of a parallel detection, a mismatch between illumination patterns and intensity measurements is corrected. Gram–Schmidt orthonormalization is further applied to the illumination patterns and corrected intensities in order to implement high-visibility GI through dynamic and complex scattering media at low sampling ratios. It is experimentally demonstrated that the proposed self-correction and orthonormalization enable high-visibility and high-efficiency GI through dynamic and complex scattering media at low sampling ratios. The proposed method offers a promising alternative to overcome the challenge faced by conventional GI in implementing high-visibility object reconstruction through dynamic and complex scattering media at low sampling ratios.
