A new method of passive image dissection suitable for use in visualizing images formed in appropriate optics by millimeter, submillimeter, or far ir radiation is proposed. The method is based upon resonance absorption of radiant energy incident on an interferometric structure formed by semiconductor panel and a planar array of piezoelectric transducers that can be addressed sequentially. The equations governing the general behavior of the device are derived and used to point out some interesting and useful qualities and to compare its characteristics with other existing methods of passive image dissection. Experimental verification of the theoretical results are also presented.
