Abstract

A novel planar-binary optical see-through visor, in which three binary optical elements, namely two couplers and one compensator, are designed to be fabricated on a planar glass slide substrate, is presented in this paper. One binary focusing coupler serves to image and couple the light into the optical plate so that the light can travel within the planar passage via total internal reflection. The other coupler directs the light out of the plate, and the compensator makes it possible for the user to see directly through the visor at the same time. Harmonic diffractive technology is employed to reduce the chromatic displacement in the visible range. The schematic of the structure and simulation results are given in this paper. Our results indicate that it is promising to utilize the planar-binary optics to cover the visible band.
