Abstract
Based on traditional ghost imaging (TGI) and differential ghost imaging (DGI), an arbitrary-matrix differential ghost imaging (ADGI) method, which can be adjusted by a self-defined matrix, is proposed. The image of stains on the lens of the reference path is successfully extracted, and it can be used to enhance the image clarity. This method can reduce the influence of occlusion in the reference path and the random interference in the image. We believe that this may provide convenience for the practical application of pseudo thermal ghost imaging.
