1. A multi-layered thin combiner (MLTC), comprising:
a plurality of discrete connectable layers, each of said plurality of discrete connectable layers having a continuous area coated with a primary partially reflective filter;
wherein each continuous area comprises a discrete fraction of an effective aperture of the MLTC;
wherein the continuous areas are configured to align, when said plurality of discrete connectable layers are connected together into a multi-layered structure, to form a continuous composite coated area and collectively define the effective aperture; and
wherein each of said continuous areas further comprises a partial overlap portion coated with a graduated partially reflective filter, and wherein two or more partial overlap portions are configured to align, when said discrete connectable layers are connected, to form a composite overlap portion operable to transmit light with uniform transmissivity throughout said composite overlap portion, the MLTC thereby being configured to merge a virtual image with a real-world image.
