It has been shown that imaging techniques involving higher order spatial correlation functions can be used to beat the classical resolution limit [1]. In case of an array of regularly arranged thermal light sources, applying specific detector positions results in a suppression of all but the highest spatial frequency component of the correlation functions. The more general case of irregularly arranged sources allows also to extract particular spatial frequency components of the correlation functions, dependent on the emitter geometry and the detector arrangement. Based on this insight we introduce the concept of remote imaging. Hereby the distance between two remote sources can be measured by use of two independent reference sources, located at a large distance with respect to the remote sources. By varying the distance between the two pairs of emitters as well as between the reference sources, the spacing between the two remote sources can be determined via analysis of the higher order spatial correlation functions.
