Abstract (en)
[origin: WO2020118406A1] A method and a device for imaging an object in a first material having a different optical density to the object. The method comprises: focusing an acoustic coherent beam to a virtual acoustic source in a fluid or an amorphous second material outside of the first material; moving the virtual acoustic source in the fluid or amorphous material such that at least a plurality of scattered beams from the virtual acoustic source scan the first material and at least the scattered beam is reflected from the object to form a reflected beam and at least one scattered beam bypasses the object to form a bypass beam, and wherein the reflected beam and the bypass beam intercept one another to form a coherent interference zone; and defocusing the coherent interference zone to provide a Fresnel fringe, the Fresnel fringe forming an image of the object.
