Lensless ghost imaging (LGI) with hollow-Gaussian modulated incoherent sources through atmospheric turbulence is investigated theoretically. The analytical formula for the point spread function of the LGI system with the hollow-Gaussian source through atmospheric turbulence is derived. By using the anti-turbulence properties of the hollow-Gaussian source, it is shown that the resolution of LGI under atmospheric turbulence can be obviously improved by properly increasing the beam order of the hollow-Gaussian incoherent source when compared with that by using traditional incoherent source.

“…Soon, Cheng et al theoretically put forward a scheme for lensless Fourier-transform imaging with a classical correlated source, and discussed its application in x-ray diffraction [5]. Compared with the entangled source, ghost imaging with classical thermal light provided more potential applications, so the classical correlated imaging has been studied extensively in recent years, both experimentally and theor etically [5][6][7][8][9][10]. Very recently, two groups experimentally realized x-ray ghost imaging [11,12], which may open the way for protocols to reduce radiation damage in medical imaging.…”

The difference in imaging quality between different ghost imaging schemes is studied by using coherent-mode representation of partially coherent fields. It is shown that the difference mainly relies on the distribution changes of the decomposition coefficients of the object imaged when the light source is fixed. For a new-designed imaging scheme, we only need to give the distribution of the decomposition coefficients and compare them with that of the existing imaging system, thus one can predict imaging quality. By choosing several typical ghost imaging systems, we theoretically and experimentally verify our results.

“…Ghost imaging with the reflective targets were analyzed theoretically and experimentally. [22][23][24] The scheme of ghost imaging lidar which can be used in the field of remote sensing was also proposed. [10,[25][26][27][28] Note that the most work focused on ghost imaging with monochromatic thermal light.…”

The coherent-mode representation theory is firstly used to analyze lensless two-color ghost imaging. A quite complicated expression about the point-spread function (PSF) needs to be given to analyze which wavelength has a stronger affect on imaging quality when the usual integral representation theory is used to ghost imaging. Unlike this theory, the coherent-mode representation theory shows that imaging quality depends crucially on the distribution of the decomposition coefficients of the object imaged in a two-color ghost imaging. The analytical expression of the decomposition coefficients of the object is unconcerned with the wavelength of the light used in the reference arm, but has relevance with the wavelength in the object arm. In other words, imaging quality of two-color ghost imaging depends primarily on the wavelength of the light illuminating the object. Our simulation results also demonstrate this conclusion.
