Abstract: Described examples include an apparatus includes a spatial light modulator configured to receive input light; and modulate the input light, to produce modulated light, where the modulated light has a pixel pattern of dark pixels and bright pixels. The apparatus also includes a diffractive optical element optically coupled to the spatial light modulator, the diffractive optical element configured to: receive the modulated light; and modulate the pixel pattern of dark pixels and bright pixels, to produce a structured light pattern, the structured light pattern having dark regions and bright regions, the bright regions each having the pixel pattern of dark pixels and bright pixels.

Abstract: Described examples include a structured light projector including a light source. The structured light projector also includes a spatial light modulator arranged to modulate light from the light source. The structured light projector also includes a diffractive optical element arranged to modulate the light from the light source. The structured light projector further includes projection optics arranged to project the light modulated by the spatial light modulator and the diffractive optical element to a target.
