Assignee: MICROSOFT TECHNOLOGY LICENSING, LLC
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A display device, comprising:
a light source configured to emit illumination light along an illumination path, the illumination light used to achieve illumination of a spatial light modulator;
the spatial light modulator configured to receive and modulate the illumination light, and emit the modulated illumination light as image light along an imaging path, wherein at least a portion of the illumination path and at least a portion of the imaging path extend through a common light path region extending along an optical axis of the display device; and
two or more optical elements positioned within the common light path region, at least one optical element of the two or more of optical elements being configured to (1) guide the illumination light as the illumination light travels through the common light path region toward the spatial light modulator, and (2) shape the image light as the image light travels through the common light path region, the two or more optical elements including a lens within the common light path region configured to both transmit the illumination light prior to modulation by the spatial light modulator, and also transmit the image light after modulation by the spatial light modulator, and the two or more optical elements including a partially cut lens positioned within the common light path region.
