摘要 提出了多模差分鬼成像技术(MWDGI)可以提高鬼成像的信噪比(SNR)。对使用旋转的毛玻璃板和空间光调制系统的两种情况的MWDGI分别做出了理论分析。研究结果表明MWDGI结合了差分鬼成像(DGI)和多模鬼成像(MWGI)的优点,能够显著提高各种类型物体的鬼成像的SNR。 The multi-wavelength differential ghost imaging (MWDGI)was proposed to improve the signal- to-noise ratio (SNR) of ghost image. We presented a theoretical analysis for the MWDGI with rotating ground glass plate and spatial light modulating system, respectively. The investigation work showed that the MWDGI uniting the advantages of differential ghost imaging (DGI)and multi-wavelength ghost imaging (MWGI) remarkably improved the SNR of ghost image obtained for all kinds of objects.
