An high quality image with was obtained in scattering media for the first time by applying the second-order correlation of illuminating light field. 

Researchers at State Key Laboratory of High Field Laser Physics ——Shanghai Institute of Optics and Fines Mechanics (SIOM/China) have obtained an image with high quality in scattering media by applying the second-order correlation of illuminating light field. [Optics Letters 36 (3), 394, 2011] 

This imaging method, for the first time (to our knowledge), leads to the separation of detection and imaging. For imaging in scattering media, when there is multiple scattering in the test path but no scattering in the reference path, because of the characteristics of imaging via the second-order correlation of light field, the effect of multiple scattering on the imaging quality may be decreased. In this Letter, imaging in scattering media with thermal light is investigated by the secondorder correlation of two light fields.
