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).
