Prior art coherent optical wave mixing has permitted two-dimensional maps from which coupled quantum transitions have been identified in molecular samples. However, extended signal accumulation times and computer processing are required for a detailed molecular analysis, which can lead to sample toxicity and difficulties in interpretation. These and other requirements are reduced by an apparatus arranged for the projection of an image that directly encodes quantum couplings from a sample. Such an apparatus includes a source component (36), a diffractive optical component (25) for generating at least three light fields (1, 2, 3) from one light field (23), one or more optical telescopes (26) and (27) wherein the transverse separation between optical paths is modified from that possible to define with a single telescope between common object and image points, a sample (11) containing said image point, and a means for resolving and detecting the angular variation of light emission from a sample. The occurrence of coupled quantum transitions or energy transfers are identified providing a means for sample analysis thereby.
