Imaging technique using spatially and temporally modulated wave front

The synthetic interferometric imaging involves the interferometric formation of a zone plate in space by the use of two stationary point sources; a zone plate is recorded for each object point through the relative motion of the object over this zone plate. This paper proposes an imaging technique in which a zone plate for each stationary object is obtained as a temporal signal. This is achieved by projecting an interference pattern on the object with two plane waves that are modulated both spatially and temporally.
