1. A head worn imaging system, comprising:
- a light source configured to generate a light beam; and
a light guiding optical element having a thickness of between 0.1 and 1.5 mm and comprising an entry portion and an exit portion,wherein the light guiding optical element is configured to propagate at least a portion of the light beam by total internal reflection,wherein the exit portion of the light guiding optical element is configured to selectively allow light addressing the exit portion to exit the light guiding optical element based on an angle of incidence of the light, andwherein the light guiding optical element allows multiplexing of light to a plurality of focal planes through the light guiding optical element.

Abstract
A head worn imaging system includes a light source configured to generate a light beam. The system also includes a light guiding optical element having a thickness between 0.1 and 1.5 mm and configured to propagate at least a portion of the light beam by total internal reflection. The system further includes an entry portion and an exit portion of the light guiding optical element configured to selectively allow light addressing the exit portion to exit the light guiding optical element based on the angle of incidence of the light, the radius of curvature of the light and/or the wavelength of the light.
