Claim One:
1. A switchable optical imaging system for transforming optical beams emanating from a display surface displaying 2-dimensional patterns and for projecting transformed optical beams in a field of view to thereby divide the field of view into one or more adjustable viewing zones, comprising: a first matrix of converging micro-lenses, with each micro-lens being optically coupled to one respective area of the display surface along a respective optical axis; a second matrix of converging micro-lenses optically coupled to the micro-lenses of the first matrix; a third matrix of converging micro-lenses coaxially aligned and rigidly jointed to the micro-lenses of the second matrix such that the second and third matrices in combination define a complex of matrices; and a displacement mechanism for axially moving the first matrix or the complex of matrices relative to each other and for transversely moving the first matrix or the complex of matrices relative to each other.
