Patent number: 11852852Abstract: A method for optical sensing includes providing a mirror comprising a central reflective region surrounded by a peripheral glare-suppressing region. A beam of light from a laser light source is directed to reflect from the central region so as to pass through an output optic along an axis toward a target scene. The light returned from the target scene through the output optic is focused onto an optical sensor, via collection optics having a collection aperture surrounding the mirror.Type: GrantFiled: October 30, 2022Date of Patent: December 26, 2023Assignee: APPLE INC.Inventors: Ariel Lipson, Itai Afek, Jonathan Hauser, Roei Remez, Moshe Kriman, Zafrir Mor

Patent number: 11320666Abstract: Optoelectronic apparatus includes a substrate and an array of light-emitting elements formed on a semiconductor die and mounted on the substrate, wherein the light-emitting elements are driven by separate, respective conductors, which are formed on the substrate. A controller drives the light-emitting elements selectively by applying drive signals to the respective conductors in order to create a pattern. One or more optical elements are mounted so as to receive light emitted from the array of light-emitting elements and include at least one diffractive optical element (DOE) configured to project the received light from the first optical element so as to create multiple replicas of the pattern, which fan out over a predefined angular range.Type: GrantFiled: February 24, 2020Date of Patent: May 3, 2022Assignee: APPLE INC.Inventor: Zafrir Mor
