  • VCSEL CHIP FOR GENERATION OF LINEAR STRUCTURED LIGHT PATTERNS AND FLOOD ILLUMINATION
    Publication number: 20230085063
    Abstract: A vertical cavity surface emitting laser (VCSEL) chip includes a structured light (SL) VCSEL array, and a fill VCSEL array. The SL VCSEL array includes a plurality of first VCSELs on a substrate. The fill VCSEL array includes a plurality of second VCSELs on the substrate. The fill VCSEL array is positioned orthogonal to the SL VCSEL array on the substrate. Light emitted from the SL VCSEL array may be used to form a bar pattern, and light from the SL VCSEL array and the fill VCSEL array together may be used to form flood illumination.
