Latest Patents

Lionel E Edwin holds a patent for "Optical systems with one-dimensional eye tracking." This invention involves a display that utilizes a waveguide to provide image light to an eye box. The system features an emitter that emits infrared light collimated at various angles relative to a collimated axis and divergent along an orthogonal axis. The waveguide propagates the infrared light and incorporates overlapping one-dimensional diffractive gratings with parallel periodic structures. Each grating diffracts a portion of the infrared light towards the eye box, allowing for effective gaze tracking. A camera captures glints of the infrared light reflected off a user's eye, facilitating accurate gaze tracking while keeping the optical emitter invisible to the user.
