Abstract
An eye tracking system for a head-mounted display (HMD) device. The system includes a lens assembly, an optical tube assembly, and an optical light guide. The optical tube assembly is coupled to the lens assembly, supporting the lens assembly and ensuring optical alignment with a display panel of the HMD device. The lens assembly is positioned close to the front end of the optical tube assembly, which is near the user's eye during use. The optical light guide transports light and is coupled to the optical tube assembly. The optical light guide includes a light input feature positioned rearward of the front end of the optical tube assembly that is configured to receive light from a light source. The optical light guide also includes a plurality of light output features positioned proximate to the front end of the optical tube assembly.
