A depth camera assembly includes an illumination source, and an imaging device. The illumination source includes one or more emitters on a single substrate, and one or more folding elements folding at least an optical path of the projected light from each emitter. Each emitter emits a respective beam of light. The imaging device captures images of the local area illuminated with the light from the illumination source. In some configurations, the depth camera assembly includes a controller that provides images to a console that determines a depth information based in part on images of the local area illuminated with the light from the illumination source, and generates a virtual object based in part on the depth information.
