ABSTRACT:
A virtual input element image projection apparatus couples a suitable lens and an optical element to increase the diverging angle of a virtual input element image or generate a plurality of portions of the virtual input element image that are coupled to form the complete virtual input element image without reducing diffraction efficiency. The projection distance for generating the virtual input element image may also be shortened.
