A device, use of the device and a method for high-contrast imaging

The present invention relates to a device, use of the device and a method for high contrast imaging, particularly suitable for imaging of moving object of interest such as gas expanding from a gas jet or physical or chemical or biological processes in material. The device for high-contrast imaging comprises a beam splitter (21) for splitting a beam (1) into a probe beam (3) and a reference beam (7), wherein the probe beam (3) is directed to an object (6); a self-imaging system (30) for receiving the probe beam (3) from the object (6) and imaging the object (6) on itself while in a preferred embodiment, the system (30) preserves the a reflected probe beam (31) divergence. The beam (3, 31) interacts with the object (6) at least twice; and the reflected probe beam (31) is further directed to the splitter (21) after the last interaction; and detection means (11) receiving the probe beam (31) from the splitter (21).
