Super-Resolution of Rotating Objects.
Abstract
It is shown that if an object passes through an interference field then a one-dimensional image can be formed along the direction of motion via synthetic aperture techniques. This technique, labeled Synthetic Interferometer Imaging depends on electronically detecting the intensity of the time varying signal scattered by the object. This detected signal is then, in general, match filtered to give the image. This technique was demonstrated using interference between two laser beams of the Hermite-Gaussian type with different transverse order number. For the case where the interference field is formed by two coherent point sources a spatial recording of the detected signal produces a simple hologram of the object. The effective (synthetic) aperture of this hologram and hence the image resolution is proportional to the recording time and is also dependent on the geometry of the system.
