ABSTRACT:
Disclosed is a method and apparatus for holographically discerning an object, using any kind of coherent wave such as microwave, millimeter wave, or sound wave. An asymmetric, dispersive medium is so positioned that some of the coherent wave scattered by the object may fall on the dispersive medium. The scattered wave passing through the medium falls on a stationary receiving antenna, and then the so received wave interferes with the reference wave to produce an interference pattern. The refraction of the scattered wave at the dispersive medium varies with the frequency of the wave and, therefore, the scattered wave impinging on the stationary antenna leaves from different positions on the dispersive medium if the frequency of the coherent wave used is varied. Thus, the interference patterns will be obtained for three-dimensional discernment of the object simply by changing the frequency of the coherent wave instead of moving the receiving antenna or the intervening medium as is done in the conventional holographic system.
