ABSTRACT:
This Patent Application describes invention in form of a design of three-dimensional (3D) autostereoscopic displays and other similar electro-optical devices, and also describes a method for reducing crosstalk in said 3D displays and in other similar electro-optical devices, such as in the electro-optical devices that perform optical switching, optical processors, optical data storage, etc. The improvement of the image quality as a result of the decrease of the size of the samples of Holographic/Diffractive Optical Element without increased crosstalk and/or superposition of extraneous images in the image reconstruction is also achieved by the use of the invention described in this Patent Application.
