1. A micro-layered structure for use in an optical projection system, the micro-layered structure comprising:
a first semi-reflective transparent layer having a first index of refraction, the first semi-reflect transparent layer having a first front surface and a first rear surface;
a second semi-reflective transparent layer having a second index of refraction different from the first index of refraction, the second semi-reflect transparent layer having a second front surface and a second rear surface, the second front surface abutting the first rear surface of the first semi-reflective transparent layer;
wherein the micro-layered structure is configured to reflect incident light as multiple reflections;
wherein a first portion of the incident light is reflected by the first front surface as a first reflection, a second portion of the incident light is reflected by the first rear surface as a second reflection, a third portion of the incident light is reflected by the second front surface as a third reflection and a fourth portion of the incident light is reflected by the second rear surface as a fourth reflection;
wherein the first reflection, the second reflection, the third reflection and the fourth reflection collectively form a projection of the image wherein the projection of the image is perceived by a user of the optical projection system to be located behind the micro-layered structure.
