Abstract: A depth camera assembly (DCA) determines depth information for a local area. The DCA includes a camera assembly and at least one illuminator. The DCA may select a subset of the VCSELs to provide illumination at any given time. The illuminator may comprise near-field VCSELs configured to generate a structured light (SL) pattern for depth sensing in the near-field and far-field VCSELs configured to generate a SL pattern for depth sensing in the far-field. The near-field VCSELs may comprise a linear emission region which is shorter than a linear emission region of the far-field VCSELs. The DCA may generate and phase shift a quasi-sinusoidal SL pattern. The DCA may phase shift the quasi-sinusoidal SL pattern by alternating which traces on the illuminator are active.
