Analysis of the ‘Anti-scattering’ Capacity of Computational Ghost Imaging System in Solid Scattering Material
Recent researches showed that the traditional ghost imaging (TGI) using pseudo-thermal light can be affected by the solid scattering material placed between the object and the light source. This scattering case might also affect the computational ghost imaging (CGI) and is considered in this paper....

| description | Recent researches showed that the traditional ghost imaging (TGI) using pseudo-thermal light can be affected by the solid scattering material placed between the object and the light source. This scattering case might also affect the computational ghost imaging (CGI) and is considered in this paper. Different from the TGI system modeled by Huygens–Fresnel theory in continuous coordinates, in CGI the use of computer-generated patterns with the controllable size (<inline-formula><tex-math notation="LaTeX">$d$</tex-math></inline-formula>) of each pixel discretizes the object space into the <inline-formula><tex-math notation="LaTeX">$d$</tex-math></inline-formula>-based pixel-grids. Therefore, how the CGI system is affected by the scatters depends on the distribution of the scattered light on these discretized grids instead of in continuous coordinates, which has not been explored. In this paper, we demonstrate that the “anti-scattering” capacity of CGI is governed by the discrete point-scattering-function (DPSF) that is determined by <inline-formula><tex-math notation="LaTeX">$\frac{{w_{0}}}{d}$ </tex-math></inline-formula>(<inline-formula><tex-math notation="LaTeX">$w_{0}$</tex-math></inline-formula>: the width of point-scattering-function of the scatters). We show that the blurry effect on the reconstructed image is visible as <inline-formula><tex-math notation="LaTeX">$d\ll\frac{{w_{0}}}{2}$</tex-math></inline-formula>, but can be highly restrained as <inline-formula><tex-math notation="LaTeX">$d$</tex-math></inline-formula> increasing to be comparable to <inline-formula><tex-math notation="LaTeX">$\frac{w_{0}}{2}$</tex-math></inline-formula> or larger. Furthermore, <inline-formula><tex-math notation="LaTeX">$d$</tex-math></inline-formula> determines the spatial resolution power of CGI. In the given CGI system, the minimum <inline-formula><tex-math notation="LaTeX">$d$</tex-math></inline-formula> of <inline-formula><tex-math notation="LaTeX">$\sim\frac{{w}_{0}}{5}$</tex-math></inline-formula> could be achieved with maintaining the behavior of “scattering-free”. |
