Application: Ultrafast illumination for structured light based eye tracking (Patent ID: US20240210677A1)
The patent filed by Meta Platforms Inc. describes an illumination system for eye tracking that utilizes a laser light source and an ultra-fast scanning micro-electromechanical system (MEMS) to reflect laser light onto the eye, generating a desired fringe pattern for controlling intensity and timing. The system includes diffractive optical elements (DOE) on the MEMS surface, grating-based illuminators on a photonic integrated circuit (PIC), and a 2D single-photon avalanche diode (SPAD) sensor or SPAD array detector on the detection side. Compressive sensing techniques are applied for processing the captured reflection of the fringe pattern, enabling the determination of a user's gaze based on the obtained 3D features of the eye surface.
The patent also includes claims for an eye tracking system that incorporates a light source providing collimated light, diffractive waveguide emitters on a PIC, MEMS adiabatic switches to direct light to the emitters, and a sensor system to capture reflections from the eye surface. A controller processes the captured reflection to determine the user's gaze based on the 3D features obtained. The system utilizes compressive sensing techniques, operates at a frequency range from 10 kHz to 100 kHz, and includes various components such as active MEMS shutter arrays, optical lenses, and different types of light sources. Overall, the patent outlines a sophisticated eye tracking system that combines advanced technologies to accurately determine a user's gaze based on reflections from the eye surface.
