    Ghost imaging (GI) is a technique to retrieve images by correlating intensity fluctuations. In this Letter, we present a novel scheme for GI referred to as second-order cumulants GI (SCGI). The image is retrieved from fluctuation information, and resolution may be enhanced compared to traditional GI. We experimentally performed SCGI image reconstruction, and the results are in agreement with theoretical predictions.


    1. Introduction

    Ghost imaging (GI) is an imaging technique based on second-order intensity correlation[110]. GI has many advantages compared to traditional imaging techniques. For example, thermal lens-less GI may be performed[11] even in the presence of atmospheric and instrumental fluctuations[1216]. The resolution is an important factor in evaluating image quality[17,18], and how to improve the resolution of GI is a key factor in the development of GI[1720].
