Abstract
A method for producing light-guide optical elements (LOEs) () each having a set of mutually-parallel partially-reflecting surfaces () located between, and oriented non-parallel to, a pair of major external surfaces, and at least one region () without partially-reflecting surfaces. The method includes bonding together parallel-faced plates () at interfaces to form a stack () of plates with partially-reflecting coatings between them. The stack is cut and polished to form a boundary plane () intersecting the interfaces, and a block () of transparent material is bonded to the stack. The resulting precursor structure (′) is sliced along parallel planes to form slices, each containing a part of the stack for the active region of the LOE and a part of the block.
