WebLimited by long acquisition time of 2D ghost imaging, current ghost imaging systems are so far inapplicable for dynamic scenes. However, it’s been demonstrated that nature images are spatiotemporally redundant and the redundancy is scene dependent. WebOct 30, 2024 · Based on the theory of ghost imaging (GI) and using the spatial power spectrum of the refractive index of ocean water, we develop a unified imaging formula for the CGI and computational ghost diffraction (CGD) operating through oceanic turbulence, and numerically analyse how the image quality can be affected by oceanic turbulence …
WebMay 10, 2024 · The influence of uneven temperature distribution on imaging quality of computational ghost imaging (CGI) in the underwater environment is investigated experimentally. It is shown that as the water temperature increases, imaging quality presents a trend from deterioration to improvement. WebJul 17, 2013 · In a ghost imaging system, the object and the imaging detector are illuminated by two correlated, spatially separated light beams, and the ghost image is obtained from intensity correlations between the two light fields. These optical correlations can occur in either the quantum or classical regime [ 1 ].
