Abstract: The present invention relates to a head-up display device comprising:



a. a transparent carrier comprising an inlet optical interface and an outlet optical interface,
b. a reflector element arranged on one portion of the outer facet of the inlet optical interface,
c. A source for projecting information, which source is capable of emitting, in the direction of the reflector element, a light beam polarized according to a main polarization and referred to as the incident beam, the incident beam arriving on the reflector element at an incidence angle and defining, with the reflector element, an incidence plane, the main polarization being a polarization contained within the incidence plane, referred to as P-polarization,
the reflector element having a greater reflectivity, over a range of incidence angles including the incidence angle, for P-polarized light than for a rectilinear polarization light perpendicular to the incidence plane, which is referred to as S-polarization.

Abstract: Architectures are provided for selectively outputting light for forming images, the light having different wavelengths and being outputted with low levels of crosstalk. In some embodiments, light is incoupled into a waveguide and deflected to propagate in different directions, depending on wavelength. The incoupled light then outcoupled by outcoupling optical elements that outcouple light based on the direction of propagation of the light. In some other embodiments, color filters are between a waveguide and outcoupling elements. The color filters limit the wavelengths of light that interact with and are outcoupled by the outcoupling elements. In yet other embodiments, a different waveguide is provided for each range of wavelengths to be outputted. Incoupling optical elements selectively incouple light of the appropriate range of wavelengths into a corresponding waveguide, from which the light is outcoupled.

Abstract: Variable-focus lenses are arranged as a lens pair that work on opposite sides of a see-through optical combiner used in a mixed-reality head-mounted display (HMD) device. An eye-side variable-focus lens is configured as a negative lens over an eyebox of the see-through optical combiner to enable virtual-world objects to be set at a close distance. The negative lens is compensated by its conjugate using a real-world-side variable-focus lens configured as a positive lens to provide an unperturbed see-through experience. For non-presbyopes, the powers of the lenses are perfectly offset. For presbyopes, the lens powers is mismatched at times to provide simultaneous views of both virtual-world and real-world objects on the display in sharp focus. Responsively an eye tracker indicating that the user is engaged in close viewing, optical power is added to the real-world-side lens to push close real-world objects optically farther away into sharp focus for the presbyopic user.
