FIG. 1.

(a) Schematic setup of the Positive-Negative Turbulence-free Ghost Imaging experiment with thermal light in which significant turbulence is introduced in its optical paths. The dark shaded beams indicate the optical path to the “bucket” and the light shaded beams indicate the optical path of the reference image. (b) The inset in the upper right depicts typical turbulence structures measured during the turbulence-free ghost imaging experiment.

FIG. 2.

Experimentally generated positive and negative turbulence-free ghost images of a letter “A” target using 10 000 frames of data measured through laboratory turbulence. Left: positive Turbulence-free Ghost Image of the letter “A”. Middle: negative turbulence-free ghost image of the letter “A”. Right: average Classical Image of the letter “A” showing the distortion caused by turbulence. This average classical image shows less distortion than the individual classical images but more distortion than the ghost images.7 The classical images were taken from the bucket arm. The “positive” (“negative”) ghost images are not adversely affected by the turbulence while the average of the classical images shows significant degredation.
