An imaging system (100; 200; 300; 400; 500) for receiving an at least partially coherent light beam being indicative of at least one parameter of movement of a moving object, the system comprising: an imaging unit (10; 20) comprising a detector (22; 308); wherein said imaging unit is selectively operable to provide an unfocused image of the object in the object plane, collect a sequence of secondary speckle patterns and determine at least one shift between regions of the object which appear in the sequence of secondary speckle patterns, to thereby provide motion data indicative of motion of the object along a tilt dimension and image data in an x-y plane; an interferometric module (24;302) configured and operable to detect an interference pattern indicative of phase shifts of the object being indicative of temporal changes along a z-axis; wherein said interferometric module comprises at least one beam splitter/combiner (304; 504) configured for receiving at least partially coherent light beam, splitting the beam into first object and reference beams; and at least one mirror arrangement (306; 506) located in the reference beam path and configured for reflecting the reference beam towards the detector through said beam splitter/combiner where the reference beam interferes with a second object beam being indicative of an object response to interaction with the first object beam, wherein said at least one mirror arrangement is configured for displacement at a predetermined frequency to induce controllable temporal modulation of the interference pattern; said interferometric module being configured such that the object and reference beams propagate along optical paths having a substantially identical path length. an imaging unit (10; 20) comprising a detector (22; 308); wherein said imaging unit is selectively operable to provide an unfocused image of the object in the object plane, collect a sequence of secondary speckle patterns and determine at least one shift between regions of the object which appear in the sequence of secondary speckle patterns, to thereby provide motion data indicative of motion of the object along a tilt dimension and image data in an x-y plane; an interferometric module (24;302) configured and operable to detect an interference pattern indicative of phase shifts of the object being indicative of temporal changes along a z-axis; wherein said interferometric module comprises at least one beam splitter/combiner (304; 504) configured for receiving at least partially coherent light beam, splitting the beam into first object and reference beams; and at least one mirror arrangement (306; 506) located in the reference beam path and configured for reflecting the reference beam towards the detector through said beam splitter/combiner where the reference beam interferes with a second object beam being indicative of an object response to interaction with the first object beam, wherein said at least one mirror arrangement is configured for displacement at a predetermined frequency to induce controllable temporal modulation of the interference pattern; said interferometric module being configured such that the object and reference beams propagate along optical paths having a substantially identical path length. <EOS>
