Lensless two-color ghost imaging from the perspective of coherent-mode representation**

Project supported by the National Natural Science Foundation of China (Grant Nos. 61771067, 61631014, 61471051, and 61401036) and the Youth Research and Innovation Program of Beijing University of Posts and Telecommunications, China (Grant Nos. 2015RC12 and 2017RC10).

(a) The first 50 eigenvalues of the coherent-mode representation of the source. (b) The first 50 decomposition coefficients of the object. (c) The reconstructed image of the double-slit (statistics over 10000 CCD frames) (the upper) and its cross-section curve (the bottom). The parameters are chosen as mm, mm, n = 50, z₁ = z = 175 mm, and λ₁ = λ₂ = 532 nm.
