1. A head worn imaging system, comprising:
a light source configured to generate a light beam;
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; and
a variable focus element configured to adjust a curvature of the light beam by adjusting a focus before the light beam enters the light guiding optical element through the entry portion,
wherein the light guiding optical element is configured to propagate at least a portion of the light beam by total internal reflection, and
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 a wavelength of the light beam.
