    • The present invention relates to a light ray shift element which provides controlled refraction of the incident ray and an optical axis displacement device using the above light ray shift element. An application of these optical devices to an interleave projection display system is demonstrated. The optical element is constructed from transparent flat plate materials containing a first optical medium and are disposed at a predetermined spacing along the optical axis. The orientation angle of the transparent flat plates with respect to the optical axis can be varied independently. A bulkhead consisting of the transparent flat plates and a second optical medium having an index of refraction different from the first optical medium, which is enclosed in a hermetic extendable seal, is utilized to provide light ray shift and optical axis displacement. By selecting the first and second optical media suitably, the angle of refraction of the incident ray can be controlled to optimize the quality of the image generated by the interleave projection system.
