Experimental Investigation of Iterative Pseudoinverse Ghost Imaging

Abstract: An iterative pseudoinverse ghost imaging (IPGI) method is proposed based on iterative denoising and pseudoinverse ghost imaging (PGI). The background noise in the imaging is eliminated in iterations by setting an appropriate threshold. The IPGI method provides a significantly larger enhancement of the peak signal-to-noise ratio (PSNR) than the PGI technique for binary objects. Experiments and data analyses are performed to evaluate the performance of the proposed method. Compared with conventional GI, differen… Show more

“…The object beam is modulated by an unknown object and measured by a bucket detector with no spatial resolution; the reference beam is collected by a detector with spatial resolution. It is an indirect imaging technology in which the two detectors are not directly used for object reconstruction, but the objects can be achieved by the associative calculation of two groups of data the detectors collected [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Therefore, ghost imaging technology can be applied in a variety of complex environments, such as imaging targets in a harsh surrounding, where traditional imaging technology may fail [16][17][18].…”

“…The appearance of ghost imaging with a classical light source has greatly enlarged the application prospect of ghost imaging. Ever since, researchers began focusing on how to improve the imaging quality and speed up the process of application exploration [6][7][8][9][10][11][12][13][14][15][26][27][28]. In the aspect of ghost imaging algorithms, differential ghost imaging (DGI) [6], as well as normalized ghost imaging (NGI) [7], turn attention to modifying the GI algorithm by means of weighting the speckle patterns for each measurement.…”
