Abstract
Systems and methods are provided for selectively incoupling light having different wavelengths into one of a plurality of waveguides. The systems and methods provided for selectively incoupling light having different wavelengths into one of a plurality of waveguides comprise a switching device comprising switchable reflective elements that can be configured to redirect incoming light towards an incoupling element associated with one of a plurality of waveguides.
Claims16
A wearable head mounted display system configured to be used by a wearer having an eye, said wearable head mounted display system comprising:
- an optical projector configured to output light to form an image;
- a plurality of waveguides for receiving said light to direct said light into the eye of a wearer;
- a frame configured to dispose the waveguides in front of said eye;
- and
- a switching device comprising a plurality of microelectromechanical systems (MEMS) mirrors disposed so as to selectively couple light into different waveguides in said plurality of waveguides.
A display device comprising:
- a waveguide;
- an incoupling optical element configured to redirect a light beam at a first wavelength from an optical source into the waveguide;
- a microelectromechanical systems (MEMS) mirror;
- and
- a controller configured to actuate the MEMS mirror such that the MEMS mirror is disposed in an optical path of the light beam and redirect the light beam towards the incoupling optical element.
A display device comprising:
- a first plurality of waveguides associated with a first depth plane, the plurality of waveguides configured to produce an image appearing to originate from the first depth plane;
- a first plurality of incoupling optical elements associated with the first plurality of waveguides, the plurality of incoupling optical elements configured to redirect light from an optical source into the plurality of waveguides;
- a microelectromechanical systems (MEMS) mirror;
- and
- a controller configured to actuate the MEMS mirror such that the MEMS mirror is disposed in an optical path of the light from the optical source and redirect said light towards the first plurality of incoupling optical elements.
