A display system comprises a light source assembly, a display assembly, a camera assembly, and a controller. The light source assembly is configured to generate visible light and infrared light. The display assembly is configured to generate image light using the visible light and to generate tracking light using the infrared light. The tracking light and the image light pass through a beam splitter prior to being projected into a local area. The camera assembly is configured to capture one or more images of the local area illuminated with the tracking light. The images are illuminated with the tracking light that passes through the beam splitter prior to be being captured by the camera assembly. The controller is configured to calculate depth information for objects in the local area using the one or more images.
