Coherent diffractive imaging
-
In this paper, we review the theoretical and experimental aspects of coherent diffractive imaging using a focused narrow-bandwidth table-top high harmonic source. The review begins with an outline of generation and characterization of the high harmonic source. Theoretical description of coherent diffractive imaging technique is then summarized. The review concludes with our recent results in imaging using a single harmonic beam selected by employing XUV focusing mirrors.

The quality of phased array and synthetic aperture ultrasonic images is limited by several factors determined by the sound propagation physics and diffraction laws. Image quality is mainly determined by: Resolution, which depends on signal bandwidth (in the axial direction) and on the aperture extent (in the lateral direction); Dynamic range, which is bounded by the ratio of the main to the sidelobes level and is related to the smallest features detection capability.
