Application: Fringe projector for depth sensing (Patent ID: US20240093984A1)
The patent filed by Meta Platforms Inc. describes an optical system designed to support eye tracking operations in a head-mounted device. The system includes a transparent layer, lasers, and output couplers that generate a fringe pattern on the user's eye. The system utilizes waveguides to split and redirect light beams, allowing for depth sensing and image capture within the device.
Furthermore, the patent outlines a head-mounted display (HMD) incorporating the described optical system, a fringe projector, and image sensors to generate image data representative of the fringe pattern. A controller within the HMD operates the laser and processes the image data to create a 3D depth map of the eyebox region. The method described involves emitting light beams, splitting them using waveguides, projecting a fringe pattern onto the user's eye, capturing images of the pattern, and generating a depth map based on these images. Additionally, the method includes modifying the laser's wavelength to alter the fringe pattern characteristics and utilizing multiple lasers to create and analyze multiple fringe patterns for depth mapping.
