Abstract: The disclosure provides a method for an electronic device including a lens; a plurality of light sources disposed on or adjacent to an edge of the lens, and configured to illuminate an eye of a user; at least one camera disposed adjacent to the edge of the lens, and configured to capture an image of the eye; and a controller configured to perform eye tracking for the user based on the image captured by the at least one camera. According to the embodiments of the disclosure, on a premise that the characteristics of the lens are not affected by the electronic device, a feasibility of capturing the eye image and quality of the image are ensured.

Abstract: An optical device is provided, including a body formed to have a concavity within which an eye box region is defined; and a plurality of addressable vertical cavity surface emitting laser (VCSEL) arrays arranged in the body of the optical device. The one or more VCSEL arrays comprise a plurality of VCSEL subarrays including independently addressable first and second VCSEL subarrays, which are controlled so as to power the first VCSEL subarray and not the second VCSEL subarray to illuminate only a first subregion of the eye box region, or to power the second VCSEL subarray and not the first VCSEL subarray to only illuminate a second subregion of the eye box region.

Abstract: An optical proximity sensor includes a housing, an optical emitter, and an optical detector. A first light guide disposed in a first chimney of the housing is configured to direct light from the optical emitter through the first chimney towards a target location. A second light guide disposed in a second chimney of the housing is configured to direct a returned portion of the light emitted from the optical emitter through the second chimney towards the optical detector.

Abstract: An optical sensor module includes a module housing defining a first compartment having a first aperture and a second compartment having a second aperture, with the second aperture spaced apart from the first aperture. A set of optical emitters is disposed in the first compartment and configured to emit light through the first aperture. A first set of optical detectors is disposed in the first compartment and configured to receive a first redirected portion of the emitted light through the first aperture. A set of optical elements is disposed in the first compartment and configured to direct at least a portion of the emitted light or the first redirected portion of the emitted light. A second set of optical detectors is disposed in the second compartment and configured to receive a second redirected portion of the emitted light through the second aperture.
