Optical transforming and modulated interference pattern of a moving object

An imaging system 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 comprising a detector;
• wherein said imaging unit is configured and operable for imaging the moving object on an image plane and generating image data indicative of the moving object in an x-y plane;
• wherein said imaging unit comprises an optical transformer configured and operable for applying a spatial image space transformation of at least one parameter of movement in a three-dimensional space into geometric relation between the parameter of the movement and a spatial image space, by converting each of different components of six degrees of freedom of movement along three axial and tilt dimensions into a lateral translation;
• said imaging system generating motion data indicative of the six degrees of freedom of movement;
• an interferometric module 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 configured for receiving at least partially coherent light beam, splitting the beam into first object and reference beams;
• and
• at least one mirror arrangement 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.
