Abstract

Experiments were performed at the Army Research Laboratory (ARL) that observed turbulence-free positive and negative thermal light ghost images from independently recorded event histories of a “bucket” photo-detector and a charged coupled device (CCD) array. The positive (negative) ghost images were computed from the “bucket” detector counts which were above (below) their means, and the ghost images were not degraded by the turbulence. This paper provides a quantum interference model which effectively explains how the “bucket” photon counts yield positive or negative ghost images with a distant CCD array.
