Paper Abstract

We have developed an imaging theory of interferometer imaging laser radar. This method probes a target using a scanning fringe pattern that is formed by two interfering beams of slightly different frequency on the surface of the probed target, then the received signal on the detector includes the information of the probed object. In other words, the scanning fringe pattern formed on the surface of the probed target is modulated by the characteristics of the object. So an image of the target being probed can be generated from the amplitude and phase of the received signs by taking the inverse Fourier transform of this information. This interferometer imaging laser radar can be superior to the mechanical scanning laser radar in the imaging rate and the spatial resolution.
