Abstract:
A projection device According to the present invention there is provided a projection device ( 30,50,100 ) comprising, a light source ( 31,61 ) which can provide light beams ( 32 a,b,c  62 a,b,c ), wherein the light beams ( 32 a,b,c  62 a,b,c ) can be used to define one or more pixels of a virtual image ( 48 ); a MEMS micro mirror ( 34 ) which is arranged to receive the light beams ( 32 a,b,c  62 a,b,c ) provided by the light source ( 31,61 ), and wherein the MEMS micro mirror ( 34 ) can oscillate about at least one oscillation axis ( 7,17 ) to scan the light beams ( 32 a,b,c  62 a,b,c ); a reflective element ( 38 ), which comprises a plurality of convex reflective projections ( 39 ), and wherein the reflective element ( 38 ) is arranged so that light beams ( 32 a,b,c  62 a,b,c ) reflected by the MEMS micro mirror ( 34 ) are incident on said convex reflective projections ( 39 ), so that the light beams ( 32 a,b,c  62 a,b,c ) are reflected by the convex reflective projections ( 39 ); a beam combiner ( 45,81 ), wherein the beam combiner is arranged to receive the light beams ( 32 a,b,c  62 a,b,c ) which are reflected by the convex reflective projections ( 39 ) wherein the beam combiner ( 45,81 ) is configured to at least partially reflect the light beams ( 32 a,b,c  62 a,b,c ) which it receives so that the light beams ( 32 a,b,c  62 a,b,c ) can form a virtual image ( 48 ) which is visible when viewed from within an eyebox ( 47 ). There is further provided a corresponding method of projecting a virtual image.

Claim (Index 33):
A method to project a virtual image, the method comprising:\n receiving, at a reflective element, a plurality of light beams, the reflective element comprising a plurality of convex reflective projections disposed on a curved plane: reflecting, at the plurality of convex projections, the plurality of light beams; receiving, at a beam combiner, the plurality of light beams reflected from the plurality of convex reflective projections; and at least partially reflecting, at the beam combiner, the plurality of light beams to form a virtual image to be viewed from within an eyebox.
