SYSTEM FOR EXTENDED HIGH FRAME RATE IMAGING WITH LIMITED-DIFFRACTION BEAMS

摘要

A system for producing a high frame rate image includes transmitting a single weighted spatial frequency signal of energy toward an object to be imaged; weighting multiple receive spatial frequency signals from the object, or by performing a spatial Fourier transform; reconstructing an image data set from the single transmitted spatial frequency signal and the multiple receive spatial frequency signals; and, reconstructing the high frame rate, high resolution and high contrast image from the image data set.
