Light is generated, and from the generated light, illumination light is formed that is projected into an image environment. The illumination light is formed by: diverging the generated light to form divergent light characterized by a light profile that is less intense in a first region centered on an optical axis of the divergent light than in a second region that at least partially rings the first region, and converting the divergent light into a plurality of illumination light patterns to be projected into the illumination environment. The illumination light patterns are each projected to a corresponding region of the illumination environment."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multiple pattern illumination optics for time of flight system","description":"Methods, systems, apparatuses, and computer program products are provided for creating multiple patterns of flood illumination for a time of flight (TOF) camera system.
