Stimulated emission based imaging techniques, especially stimulated emission microscopy, are well established and well documented techniques in the realm of biomedical applications. The utilization of a stimulated emission signal offers a variety of advantages over classical linear optical imaging, especially for the identification of biological specimens with high spatial resolution in three dimensions. There is, however, one aspect of the inherent properties of stimulated emission that so far has not received much attention and has not been utilized to its full potential. This aspect, namely the spatial coherence of the stimulated emission signal with the incoming stimulation light, can be utilized for long-distance signal detection of biomedical specimens. The feasibility of this approach is presented here.
