Principle of subtraction ghost imaging in scattering medium

Scattering medium in light path will cause distortion of the light field, resulting in poor signal-to-noise ratio (SNR) of ghost imaging. The disturbance is usually eliminated by the method of pre-compensation. We deduce the intensity fluctuation correlation function of the ghost imaging with the di...

Description
Summary:Scattering medium in light path will cause distortion of the light field, resulting in poor signal-to-noise ratio (SNR) of ghost imaging. The disturbance is usually eliminated by the method of pre-compensation. We deduce the intensity fluctuation correlation function of the ghost imaging with the disturbance of the scattering medium, which proves that the ghost image consists of two correlated results: the image of scattering medium and the target object. The effect of the scattering medium can be eliminated by subtracting the correlated result between the light field after the scattering medium and the reference light from ghost image, which verifies the theoretical results. Our research may provide a new idea of ghost imaging in harsh environment.
