Note(s): Generally, the demands of maintaining a spatially coherent bean at optical frequency is difficult over long range thereby limiting the usefulness of the technique for image formation in turbid media. The authors describe a variation of the spatial interferometric technique that relies upon projected spatial gratings with subsequent detection against a quasi-coherent return signal. The method is advantageous in not requiring temporal coherence between reference and signal beams. Coherency of the spatial beam allow detection of the direction return, while scattered light appears as a noncoherent noise term. The theoretical foundation of the method and initial results for turbid media are developed.
